A Note on the Classification of Linking Pairings on 2 Groups
... given linking pairing, we first use the description of the p-torsion of the first integral homology given in [5] to find a Seifert manifold whose first integral homology is isomorphic to the underlying group of the ...

Learning together on line: Student and staff experience of interprofessional on line groups
... ‘when we went through that process, critiquing briefing paper1 and 2, I learned quite a lot from other people, saw their different styles, etc. I realised that academically possibly I’m not as bad as I think I am. ...

2 groups, 2 characters, and Burnside rings
... There is a critical difference between a 2-module and a 2-representation of K. An action of e G on A-Mod for an arbitrary associative algebra A could be hard to pinpoint: thanks to Theorem 2.6 we need to ...

On minimal artinian modules and minimal artinian linear groups
... Let again F be a field, A a vector space over F , G ≤ GL(F , A). We want to consider the situation when A is a minimal artinian F G-module. This consideration will lead us to the fact that the group G is lying in the ...

2-Selmer groups and Heegner points on elliptic curves
... When the class number of L is odd, the Birch and Swinnerton-Dyer conjecture predicts that E should have rank one over Q(i). To construct such a point on E, we study Heegner points on Shimura curves with non-maximal level ...
