The purpose of this note is to describe some algebraic conditions on a Banach algebra which force it to be finite dimensional. One of the main results in Theorem 2 which states that for a locally compact group G, G is compact if there exists a measure μ in Soc(L1(G)) such that μ(G) 6= 0. We also prove that G is finite if Soc(M(G)) is closed and every nonzero left ideal in M(G) contains a minima...

Goto numbers g(Q) = max{q ∈ Z | Q : m is integral overQ} for certain parameter ideals Q in a Noetherian local ring (A,m) with Gorenstein associated graded ring G(m) = ⊕ n≥0 m /m are explored. As an application, the structure of quasisocle ideals I = Q : m (q ≥ 1) in a one-dimensional local complete intersection and the question of when the graded rings G(I) = ⊕ n≥0 I /I are Cohen-Macaulay are s...

<abstract><p>Let $ R be a G graded commutative ring and M $-graded $-module. The set of all second submodules is denoted by Spec_G^s(M), it called the spectrum $. We discuss rings with Noetherian prime spectrum. In addition, we introduce notion Zariski socle explore their properties. also investigate Spec^s_G(M) topology from viewpoint being space.</p></abstract>

For a fairly general reductive group G/Qp , we explicitly compute the space of locally algebraic vectors in the Breuil-Herzig construction Π(ρ)ord, for a potentially semistable Borel-valued representation ρ of Gal(Q̄p/Qp). The point being we deal with the whole representation, not just its socle – and we go beyond GLn(Qp). In the case of GL2(Qp), this relation is one of the key properties of the...

A right R-module M is called a generalized q.f.d. module if every M-singular quotient has finitely generated socle. In this note we give several characterizations to this class of modules by means of weak injectivity, tightness, and weak tightness that generalizes the results in [25], Theorem 3. In particular, it is shown that a module M is g.q.f.d. iff every direct sum of M -singular M -inject...

This article is a contribution to the study of block-transitive automorphism groups of 2-(v, k, 1) block designs. Let D be a 2-(v, k, 1) design admitting a block-transitive, pointprimitive but not flag-transitive automorphism group G. Let kr = (k, v − 1) and q = p f for prime p. In this paper we prove that if G and D are as above and q > (3(krk − kr + 1)f) , then G does not admit a simple group...
