This is no longer true for nontrivial A , even if A is a sheaf of Azumaya algebras over an abelian or K3 surface X: If Aη is not just a full matrix algebra over k(X ), then
(For a topological space in general this is a preorder, not necessarily anti- symmetric, but for a T0 space, as also for a locale, it is a partial order. A space is T1 iff
In relation with the intersection of the Andreotti-Mayer loci with the boundary of the moduli space A g we study subvarieties of principally polarized abelian varieties ( B,
In [4], a protolocalisation of a homological (see [3]) or a semi-abelian category (see [19]) is defined as a full reflective subcategory which is still regular, with a reflection
Shoda also showed that when a finite Abelian group is expressed as the direct product of primary Abelian groups whose orders are powers of distinct primes, the automorphism group of
In this paper we determine the normality of Cayley digraphs of valency 2 on the groups of order pq and also on non-abelian finite groups G such that every proper subgroup of G
It is known that stop loss is an optimal reinsurance arrangement under the pure risk premium calculation (see Daykin et al., 1993) so our solution coincides with this special
If an abelian group A is eectively hp, ωi-decomposable, then there exists a computable enumeration ν of A for which the cyclic summand A∅ is computably enumerable in A, ν... Indeed, in
