We make an observation which enables one to deduce the existence of an algebraic stack of log maps for all generalized Deligne– Faltings log structures (in particular simple normal crossings divisor) from the simplest case with characteristic generated by N (essentially the smooth divisor case).

We provide a micro-local necessary condition for distinction of admissible representations real reductive groups in the context spherical pairs. Let $\bf G$ be complex algebraic group, and H\subset subgroup. $\mathfrak{g},\mathfrak{h}$ denote Lie algebras H$, let $\mathfrak{h}^{\bot}$ annihilator $\mathfrak{h}$ $\mathfrak{g}^*$. A $\mathfrak{g}$-module is called $\mathfrak{h}$-distinguished if ...

let r be a ring,  be an endomorphism of r and mr be a -rigid module. amodule mr is called quasi-baer if the right annihilator of a principal submodule of r isgenerated by an idempotent. it is shown that an r-module mr is a quasi-baer module if andonly if m[[x]] is a quasi-baer module over the skew power series ring r[[x; ]].

Let Λ be a lattice in an n-dimensional Euclidean space E and let Λ′ be a Minkowskian sublattice of Λ, that is, a sublattice having a basis made of representatives for the Minkowski successive minima of Λ. We extend the classification of possible Z/dZ-codes of the quotients Λ/Λ′ to dimension 9, where dZ is the annihilator of Λ/Λ′.

Inspired by Faugère and Mou’s sparse FGLM algorithm, we show how using linear recurrent multi-dimensional sequences can allow one to perform operations such as the primary decomposition of an ideal, by computing the annihilator of one or several such sequences.
