A characterization of normal subgroups via n-closed sets
subgroup normal subgroup left coset n-closed set
2011/9/20
Abstract: Let (G, *) be a semigroup, D subset of G, and n >= 2 be an integer. We say that (D, *) is an n-closed subset of G if a_1* ... *a_n in D for every a_1, ..., a_n in D. Hence every closed set i...
A maximin characterization of the escape rate of nonexpansive mappings in metrically convex spaces
maximin characterization escape rate of nonexpansive mappings

We establish a maximin characterization of the linear escape rate of the orbits
of a nonexpansive mapping on a complete (hemi-)metric space, under a mild form
of Busemann’s nonpositive curvature con...
A characterization of Büchi's integer sequences of length 3

We give a new characterization of generalized B\"uchi sequences (sequences whose sequence of squares has constant second difference $(a)$, for some fixed integer $a$) of length 3 over the integers an...
We prove that a C1,1-smooth bounded domain D in Cn is linearly convex if and only if the convex hull of any two discs in D with common center lies in D.
Let $C$ be a cone and consider a quasi-norm $p$ defined on it. We study the structure of the couple $(C,p)$ as a topological space in the case where the function $p$ is also monotone. We characterize ...
A CHARACTERIZATION OF GENERALIZED FRAME MRAs DERIVING ORTHONORMAL WAVELETS
orthonormal wavelets generalized frame MRA non-MRA wavelets
2007/12/12
In 2000, Papadakis announced that any orthonormal wavelet must be derived by a generalized frame MRA (GFMRA). In this paper, we give a characterization of GFMRAs which can derive orthonormal wavelets,...

Characterization Of Left Artinian Algebras Through Pseudo Path Algebras
Characterization Left Artinian Algebras Pseudo Path Algebras
2018/4/20
In this paper, using of pseudo path algebras, we generalize the Gabriel’s Theorem on elementary algebras to left Artinian algebras over a field k when the quotient algebra can be lifted,in particular,...
In this work, presented is a partial characterization of a perfect locally nilpotent p-group in which every proper subgroup is nilpotent-by-Chernikov.
