Ogura, Kinnoseke's note / Theory of the infinite series/Sakai,Y.

In this paper we show how to obtain a result closely analogous to the McAlister theorem for a certain class of inverse semigroups with zero, based on the idea of a Brandt

Abstract The representation theory (idempotents, quivers, Cartan invariants, and Loewy series) of the higher-order unital peak algebras is investigated.. On the way, we obtain

In this context, the Fundamental Theorem of the Invariant Theory is proved, a notion of basis of the rings of invariants is introduced, and a generalization of Hilbert’s

Goal of this joint work: Under certain conditions, we prove ( ∗ ) directly [i.e., without applying the theory of noncritical Belyi maps] to compute the constant “C(d, ϵ)”

Definition An embeddable tiled surface is a tiled surface which is actually achieved as the graph of singular leaves of some embedded orientable surface with closed braid

Theorem 4.1 Two flocks of a hyperbolic quadric in PG ( 3 , K ) constructed as in Section 3 are isomorphic if and only if there is an isomorphism of the corresponding translation

We study the classical invariant theory of the B´ ezoutiant R(A, B) of a pair of binary forms A, B.. We also describe a ‘generic reduc- tion formula’ which recovers B from R(A, B)

Every pseudo-functor on G defines and is defined by a Grothendieck fibration F −→ G and here the fibrations defined by factor sets are precisely the extensions of G, with those
