Fusions in N-interior G-algebras

2002
As in §5, G is a finite group, N is a normal subgroup of G and A is an N-interior G-algebra; moreover, we may assume that A is inductively complete. It is already clear that G acts on the set of all the pointed groups on A; furthermore, if H s is a pointed group on A then any x E G naturally determines a group homomorphism k x : H → H x such that k x ...

Divisors on N-interior G-algebras

2002
Let G be a finite group; our main purpose is the study of the group algebra OG and of any 0G-module M or, equivalently, any group homomorphism G → Endo(M)*, where M is an O-free O-module. More generally, we may consider any group homomorphism G → A*, where A is an 0-algebra; for instance, whenever cp: G → Aut(B) is an action of G on an O-algebra B, the

Not Every Splitting Heyting or Interior Algebra is Finitely Presentable

Studia Logica, 2012
A pair \(V_1, V_2\) of subvarieties of a variety \(V\) is called a splitting pair if one of them is not a subvariety of the other and for every subvariety \(W\) of \(V\) either \(V_1\) or \(V_2\) is a subvariety of \(W\). It is known that, if \(V_1, V_2\) is a splitting pair, then the variety \(V_1\) is generated by a finitely generated subdirectly ...

Interior architecture of involutive WE-algebra

Asian-European Journal of Mathematics
The concept of involutive weak exchange algebras (involutive WE-algebras, for short) was introduced in 2025 by Walendziak. In this paper, we look at both the internal architecture of involutive WE-algebras and some of their substructures.

An effective representation for finitely generated free interior algebras

Algebra Universalis, 1985
An interior algebra (IA) is in fact a closure algebra in which one works with the interior operator \(I=\rceil C\rceil\) instead of the closure operator C. An I-model is the algebraic version of the concept of Kripke model for S4. The author obtains a representation of every finitely generated free IA as an IA of subsets of the set-theoretical union of

On the local structure of Hecke DG-interior algebras

1999
Keep all the notation of Section 4, set $${A^{..}} = Ind_{{H^{..}}}^{G \times G'}\left( {{B^{..}}} \right)and\,\hat A = Ind_{{H^{..}}}^{G \times G'}{\left( {{B^{..}}} \right)^{1 \times G'}}$$ (5.1.1) and consider a point â of G on Â; in this section we determine a defect pointed group of G â and the corresponding source algebra and ...

Brauer sections in basic induced DG-interior algebras

1999
In Section 7 we have shown that the existence of a suitable stable O-basis in a Morita equivalence between two blocks has strong consequences on the relationship between these blocks. As we will show in Section 19, a generalization of this phenomenon appears in Rickard equivalences between blocks.

Brauer sections in basic Hecke DG-interior algebras

1999
We keep all the notation of Section 16 and we assume again that B .. ≅ E(B ..), so that A .., Â and Â’ still coincide with their Higman envelopes (cf. Corollary 14.21 and 15.7.1). In this section we analyze a particular kind of local tracing triples on Â, A .. and OG’ (cf.
