where A and B are unital R-algebras and M is an (A, B)-bimodule. This algebra ᐁ, en- dowed with the usual formal matrix addition and multiplication, will be called a general- ized triangular matrix algebra. Many widely studied algebras, including upper-triangular matrix algebras, block-triangular matrix algebras, nest algebras, semi-nest algebras, and triangular Banach algebras, may be viewed as triangular algebras.

Accounting Games: Using Matrix Algebra in Creating the Accounting Models

Accounting Games: Using Matrix Algebra in Creating the Accounting Models

The methods of accounting modeling (from recording transactions to financial reporting) basically repeat the steps implemented in practice, by using certain numerical examples. Still the visible variety of accounting techniques complicates accounting system conceivability. The main assumption here relates to the evidence that one of the effective tools of creating accounting models can be mathematical modeling, particularly, the one which uses basic notions and operations of matrix algebra.

Analysis  of  a  key  exchange  protocol  based  on  tropical  matrix  algebra

Analysis of a key exchange protocol based on tropical matrix algebra

In this paper we analyze a key-exchange protocol based on tropical matrix algebra proposed in [4, Section 2]. Ideas similar to [4] were used before in the “classic” case, i.e., for algebras with familiar addition and multiplication. However in classic case these schemes were shown to be vulnerable to various linear algebra attacks. The idea to use an algebra with another addition and multiplication came as an attempt to avoid those attacks, as there are no known algorithms for solving systems of linear equations in tropical sense (it is an active field of research currently).

Fundamentals of Matrix Algebra

Fundamentals of Matrix Algebra

Technology Note: In the previous sec on, we learned how to find the reduced row echelon form of a matrix using Gaussian elimina on – by hand. We need to know how to do this; understanding the process has benefits. However, actually execu ng the process by hand for every problem is not usually beneficial. In fact, with large systems, compu ng the reduced row echelon form by hand is effec vely impossible. Our main concern is what “the rref” is, not what exact steps were used to arrive there. Therefore, the reader is encouraged to employ some form of technology to find the reduced row echelon form. Computer programs such as Mathema ca, MATLAB, Maple, and Derive can be used; many handheld calculators (such as Texas Instruments calculators) will perform these calcula ons very quickly.

Linear scaling density functional simulations of charged point defects in Al2O3 using hierarchical sparse matrix algebra

Linear scaling density functional simulations of charged point defects in Al2O3 using hierarchical sparse matrix algebra

given atom I overlaps a funtion on a dierent atom J , then all the funtions on both atoms overlap, giving rise to a blok of m J × n I matrix elements whih are all nonzero, where n I is the number of (olumn-) funtions on atom I and m J is the number of (row-) funtions on atom J . Therefore, rather than indexing individual nonzero elements, a large saving in both memory and CPU time is obtained by indexing nonzero atom-bloks. This form of sparse bloked

The universal enveloping algebra of the Schrödinger algebra and its prime spectrum

The universal enveloping algebra of the Schrödinger algebra and its prime spectrum

described in [12]: Each such primitive ideal is the annihilator of a simple highest weight U (s)- module with nonzero central charge, [12, Corollary 30]. In [12], the author mentioned that “the problem of classification of primitive ideals in U (s) for zero central charge might be very difficult”. In [5], using the classification of prime ideals of the algebra A := U (s)/(Z) ([5, Theorem 2.8]), a classification of primitive ideals of U (s) with zero central charge is given. In this paper, using a different (ring theoretic) approach, all the primitive ideals (including with zero central charge) are classified and their generators are given explicitly, see Theorem 4.4.

ALGEBRA IN MATHEMATICS

ALGEBRA IN MATHEMATICS

Also, the unification of the mathematical concepts can be done easily with the help of algebra and hence, it is known as an important part of Mathematics. In algebra, usually, there is an involvement of the numbers and operations in terms of geometry and data analysis. Hence, algebra can be regarded as a simple language which is used to solve those problems which are not solved with the help of numbers alone. Here modeling of the real-world problems is done with the help of the symbols like the alphabets x,y and z etc for the representation of the numbers. The current paper highlights the role of algebra in mathematics.

Applications. Applications and computing are interesting and vital aspects of the subject. Consequently, each chapter closes with a selection of topics in those areas. These give a reader a taste of the subject, discuss how Linear Algebra comes in, point to some further reading, and give a few exercises. They are brief enough that an instructor can do one in a day’s class or can assign them as projects for individuals or small groups. Whether they figure formally in a course or not, they help readers see for themselves that Linear Algebra is a tool that a professional must have.

Vector Algebra

Vector Algebra

So far we have studied about addition and subtraction of vectors. An other algebraic operation which we intend to discuss regarding vectors is their product. We may recall that product of two numbers is a number, product of two matrices is again a matrix. But in case of functions, we may multiply them in two ways, namely, multiplication of two functions pointwise and composition of two functions. Similarly, multiplication of two vectors is also defined in two ways, namely, scalar (or dot) product where the result is a scalar, and vector (or cross) product where the result is a vector. Based upon these two types of products for vectors, they have found various applications in geometry, mechanics and engineering. In this section, we will discuss these two types of products.

On the eigenvector algebra of the product of elements with commutator one in the first Weyl algebra

On the eigenvector algebra of the product of elements with commutator one in the first Weyl algebra

inner derivation ad(a) acts locally nilpotently. Little is known about these algebras in the case when N(a) 6= C(a). In particular, it is not known of whether these algebras are finitely generated or Noetherian. Though, a positive answer to Dixmier’s Fourth Problem [8], which is still open, would imply that the algebras N (a) are finitely generated and Noetherian. In case of homogeneous elements of the Weyl algebra A 1 , a positive answer to Dixmier’s Fourth Problem was given in [4].

Multisorted Tree Algebra

Multisorted Tree Algebra

In this paper we have introduced a hierarchical algebraic structure called multisorted tree algebra. A brief description of results in multisorted algebra has been given in the first section. Then the concept of aggregation operator has been presented as an operator that generatesa Σ -algebra from different other Σ -algebras. It has also been shown that aggregation operators generate a Σ -homomorphism form a given family of Σ -homomorphisms between the aggregated Σ -algebras. Next, multisorted tree algebra has been constructed by placing multisorted algebra at the bottom of a hierarchy, and by placing at other nodes the aggregation of multisorted algebra placed at their immediate subordinate’s nodes. Furthermore, an analysis about the features and the place of multisorted tree algebra in the universal algebra theory has been briefly discussed. Among the perspectives generated by this paper, investigations on mathematical features and approaches to the study of multisorted tree algebra are necessary. One of the major reasons to engage in these further studies is the fact that they represent a hierarchy of algebraic structures that cannot be classified in classic varieties of universal algebra theory and also, they are not graphs of categories of universal algebras of given signature. The multisorted tree algebra concept may also be expanded by investigating aggregations of universal algebras of different signatures, or the construction of aggregations on a graph that are not trees. Among the application perspectives, multisorted tree algebra seems to give to computer scientists a different abstract data type described as a hierarchy of data types. It’s not pretentious to think that this new concepts could also give an approach to assemble abstract data type architectures and therefore expand results where classic universal algebras has contributed in theoretical computer science domains including for example Ë -calculus [18], type theory [19], data structures [20] and algebraic specification [21, 7].
