On the perfectness of C^{∞,s}-diffeomorphism groups on a foliated manifold [PDF]
Opuscula Mathematica, 2008 The notion of \(C^{r,s}\) and \(C^{\infty,s}\)-diffeomorphisms is introduced. It is shown that the identity component of the group of leaf preserving \(C^{\infty,s}\)-diffeomorphisms with compact supports is perfect.

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 ...

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.

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 ...

On the boundedness of equivariant homeomorphism groups [PDF]
Opuscula Mathematica, 2018 Given a principal \(G\)-bundle \(\pi:M\to B\), let \(\mathcal{H}_G(M)\) be the identity component of the group of \(G\)-equivariant homeomorphisms on \(M\). The problem of the uniform perfectness and boundedness of \(\mathcal{H}_G(M)\) is studied.

Distance perfectness of graphs [PDF]
, 1999 In this paper, we propose a generalization of well known kinds of perfectness of graphs in terms of distances between vertices. We introduce generalizations of α-perfect, χ-perfect, strongly perfect graphs and we establish the relations between them ...

Criterion for the cosemanticness of the Abelian groups in the enriched signature
Қарағанды университетінің хабаршысы. Математика сериясы, 2018 In the present paper we give a criterion of the cosemanticness relative to the Jonsson spectrum of the model in the class of Abelian groups with a distinguished predicate.

Forbidden induced pairs for perfectness and ω-colourability of graphs [PDF]
, 2022 We characterise the pairs of graphs {X, Y} such that all {X, Y}-free graphs(distinct from C5) are perfect. Similarly, we characterise pairs {X, Y} such that all {X, Y}-free graphs (distinct from C5) are ω-colourable (that is, their chromatic number is ...

Recognizing the P_4-structure of claw-free graphs and a larger graph class [PDF]
Discrete Mathematics & Theoretical Computer Science, 2002 The P_4-structure of a graph G is a hypergraph \textbfH on the same vertex set such that four vertices form a hyperedge in \textbfH whenever they induce a P_4 in G.
