### SOLVABILITY OF A NORMAL SUBGROUP IN RELATION TO ITS CHARACTER DEGREES

Ker = (g G: (g) = (1) Characters are class functions i.e. they take a constant value on a given conjugacy class. Isomorphic representations have the same characters and if a representation is the di- rect sum of subrepresentations, then the cor- responding character is the sum of the char- ABSTRACT

### Bipartite divisor graph for the set of irreducible character degrees

Proof. As G is nonsolvable, Proposition 2 implies that B(G) is disconnected. Since B(G) is a union of paths, we deduce that ∆(G) is triangle-free. Now [21, Theorem A] implies that | ρ(G) | ≤ 5. Also [21, Lemma 4.1] verifies that there exists a normal subgroup M of G such that G/N is an almost simple group with socle M/N . Furthermore ρ(M) = ρ(G). Now it follows from Ito-Michler and Burnside’s p a q b theorems that | ρ(M/N ) | ≥ 3, so | ρ(G) | ≥ | ρ(M/N ) | ≥ 3. Hence 3 ≤ | ρ(G) | ≤ 5. In Lemma 5 we observe that if | ρ(G) | = 5, then G ≃ P SL(2, 2 n ) × A, where A is an abelian group and | π(2 n ± 1) | = 2. This implies that n(B(G)) = 3. On the other hand, since G is a nonsolvable group, by [10, Theorem 6.4] we conclude that n(B(G)) = 3 if and only if G ≃ P SL(2, 2 n ) × A, where A is an abelian group and n ≥ 2. So we may assume that | ρ(G) | ≤ 4 and n(B(G)) = 2. As n(Γ(G)) = n(B(G)) = 2, [10, Theorem 7.1] implies that one of the connected components of Γ(G) is an isolated vertex and the other one has diameter at most two. Therefore | cd(G) | ∈ { 4, 5 } .

### Characterization of some simple $K_4$-groups by some irreducible complex character degrees

| G/K | | | Out(K/H ) | = 2 or 3. Thus | H | | 2 2 · 3 · 7 2 · 19 or | H | | 2 2 · 7 2 · 19 and hence, Lemma 1.7 guarantees that H is solvable. Therefore, an easy calculation and Lemma 1.4 show that a 19-Sylow subgroup of H is normal in H and so, it is normal in G. Thus G has a normal abelian 19-Sylow subgroup and hence, Ito’s theorem implies that χ(1) = 2 3 · 3 · 19 | [G : P ], which is impossible. Therefore K/H ∼ = L 3 (7) and hence, G = K ∼ = L 3 (7), as desired.

### Detecting the prime divisors of the character degrees and the class sizes by a subgroup generated with few elements

would have an abelian normal Sylow p-subgroup against our assumption. So P Y /Y is a nontrivial abelian normal subgroup of K/Y ∼ = L and this is possible only if N ∼ = P Y /Y is an elementary abelian p-group. In this case N = soc(L) has a complement, say T , in L. In particular { (t, . . . , t) ∈ L t | t ∈ T } is a complement of N t in L t and all the minimal normal subgroups of L t are T -isomorphic to N.

### <p>Implication Of Character Traits In Adherence To Treatment In People With Gout: A Reason For Considering Nonadherence As A Syndrome</p>

This interpretation clari ﬁ es also the enigmatic fact that, in randomised clinical trials, patients allocated to placebo consistently exhibit a higher survival rate when they are adherent, 46,47 leading to explanations using the “ healthy adherer ” concept for this fascinating observation. 46 The data reported herein support this explanation by demon- strating a strong link between adherence to medication and dietary and exercise recommendations and other protective behaviours. We suggest that character traits such as patience and obedience and, possibly, others such as ﬁ de- lity to habits, optimism, joy and caution 29 have a real causal effect, leading, when they are present, to a “ healthy adherer ” phenotype. By “ real causal effect ” , we mean that it is not only a statistical link between observations but a mechanism, in the same sense that insulin causes a decrease in blood glucose concentration. 26,30 The absence of these positive character traits leads to conditions of what we propose to dub a “ nonadherence syndrome ” :

### Nilpotent L-subgroups and the Set Product of L-subsets

Since the level subsets of η and µ are subgroups of G, η and µ are L-subgroups of G. As η ⊆ µ, η is an L-subgroup of µ. Now in view of the fact that every subgroup of a nilpotent group is nilpotent, it follows that all the level subsets of η are nilpotent subgroups of the corresponding level subsets of µ. Therefore the converse of Theorem 4.1[3], implies that η is a nilpotent L-subgroup of µ.

### On locally soluble $$\mathrm A \mathrm F \mathrm N$$-groups

contradiction shows that F/H is finite. Put B/H = (P/H) p . If P/B is infinite then P/B is not finitely generated. Therefore the cocentralizer of P in A is a noetherian R-module. By corollary 5 G = N D(G). Since G/P is finite, it follows that the cocentralizer of G in A is a noetherian R-module by lemma 1. This contradiction proves that (P/H)/(B/H) is finite. By lemma 3 [9] P/H = (V /H) × (D/H) where D/H is divisible and V /H is finite. D is a G-invariant subgroup. Put K = D. Since G/D is finite, it is suffices to apply lemma 4.

### Professional Educator Character of Pedagogical Student in Medan State University

Character comes from Greek word, “charassein”, which means goods or equipment to scratch, which was then understood as stamp (Adisusilo, 2012). Character come from language of ancient Greek “karasso”, meant “to mark”, namely to sign or to carve. Within Kamus Besar Bahasa Indonesia (2003) it was written that character was unique feature, character, temperament owned by individual that differentiates individuals to one another. Character is way of thinking and acting to be each individual’s unique characteristic to live and collaborate either in milieu of family, community, or nation and state (Suyanto, 2010). Character is the sum of total or integration of all such marking (traits) to yield unfield whole which reveals the nature (the character) of situation, of an event or a person (Reber, 1985) (Hendrojuwono, 2008, as proposed by Menanti, 2012). Character is an integration characteristic owned by individual, that differentiates one individual to one another in adapting self to environment (Menanti, 2009, 2012). Character is unique characteristic of a person or a number of persons that covers value, competence, moral capacity, and resiliency in facing difficulty and challenge (National Policy on character building for Indonesia Year 2010- 2025, 2013). Ghozali (Sani, 2011) considered that character implied value of good character, sponteanity, already integrated in self when doing behavior.
