On perfectness of Grothendieck's pairing for the l-parts of component groups
Journal Fur Die Reine Und Angewandte Mathematik, 2001 We prove the perfectness of Grothendieck's pairing on l-parts of component groups of an abelian variety and its dual when l is prime to the residue characteristic.

PERFECTNESS OF THE ANNIHILATOR GRAPH OF ARTINIAN COMMUTATIVE RINGS [PDF]
Journal of Algebraic Systems, 2023 Let $R$ be a commutative ring and $Z(R)$ be the set of its zero-divisors.The annihilator graph of $R$, denoted by $AG(R)$ is a simple undirected graph whose vertexset is $Z(R)^*$, the set of all nonzero zero-divisors of $R$, and two distinct ...

On the structure of certain nontransitive diffeomorphism groups on open manifolds [PDF]
Opuscula Mathematica, 2012 It is shown that in some generic cases the identity component of the group of leaf preserving diffeomorphisms (with not necessarily compact support) on a foliated open manifold is perfect. Next, it is proved that it is also bounded, i.e.

Similarities of Jonsson spectra’s classes
Қарағанды университетінің хабаршысы. Математика сериясы, 2023 The study of syntactic and semantic properties of a first-order language, generally speaking, for incomplete theories, is one of the urgent problems of mathematical logic.

The matrix Jacobson graph of finite commutative rings
Electronic Journal of Graph Theory and Applications, 2022 The notion of the matrix Jacobson graph was introduced in 2019. Let R be a commutative ring and J(R) be the Jacobson radical of ring R. The matrix Jacobson graph of ring R size m × n, denoted 𝔍(R)m × n, is defined as a graph where the vertex set is Rm ...

Two New Estimators for a Normal Coefficient of Variation based on Ranked Set Sampling [PDF]
المجلة العلمية للدراسات والبحوث المالية والإدارية, 2021 This article addresses the estimation for the coefficient of variation (CV) of the normal distribution considering ranked set sampling. Using EM algorithm and linear interpolation technique, two new estimators for the CV are proposed.

Relative-perfectness of discrete gradient vector fields and multi-parameter persistent homology [PDF]
, 2021 The combination of persistent homology and discrete Morse theory has proven very effective in visualizing and analyzing big and heterogeneous data. Indeed, topology provides computable and coarse summaries of data independently from specific coordinate ...

Some Indices over a New Algebraic Graph
Journal of Mathematics, 2021 In this paper, we first introduce a new graph ΓN over an extension N of semigroups and after that we study and characterize the spectral properties such as the diameter, girth, maximum and minimum degrees, domination number, chromatic number, clique ...

Journal of Asian Architecture and Building Engineering, 2023 The construction energy consumption (CEC) is about 35% of entire energy consumption (EC), of which 50% is for cooler air-conditioner. The practical cooling EC is relevant to the dynamic thermal performance of cooler air-conditioner.
