On the structure of certain nontransitive diffeomorphism groups on open manifolds [PDF]

open access: yesOpuscula 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.

On the uniform perfectness of equivariant diffeomorphism groups for principal G manifolds [PDF]

open access: yesOpuscula Mathematica, 2017
We proved in [K. Abe, K. Fukui, On commutators of equivariant diffeomorphisms, Proc. Japan Acad. 54 (1978), 52-54] that the identity component \(\text{Diff}\,^r_{G,c}(M)_0\) of the group of equivariant \(C^r\)-diffeomorphisms of a principal \(G\) bundle \

The matrix Jacobson graph of finite commutative rings

open access: yesElectronic 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 ...

Some Indices over a New Algebraic Graph

open access: yesJournal 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 ...

A novel method for building air conditioning energy saving potential pre-estimation based on thermodynamic perfection index for space cooling

open access: yesJournal 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.
