Gerty Cori, a Life Dedicated to Chemical and Medical Research

open access: yesFoundations, 2023
This article shows the life and work of Gerty Cori, a woman born in Czechoslovakia and who later became a naturalized American, who spent her whole life researching, together with her husband, in the laboratory to find the cause of some diseases ...

Topology and topological sequence entropy [PDF]

open access: yesScience China Mathematics, 2019
Let $X$ be a compact metric space and $T:X\longrightarrow X$ be continuous. Let $h^*(T)$ be the supremum of topological sequence entropies of $T$ over all subsequences of $\mathbb Z_+$ and $S(X)$ be the set of the values $h^*(T)$ for all continuous maps $T$ on $X$.

On the Wiener Complexity and the Wiener Index of Fullerene Graphs

open access: yesMathematics, 2019
Fullerenes are molecules that can be presented in the form of cage-like polyhedra, consisting only of carbon atoms. Fullerene graphs are mathematical models of fullerene molecules.

TOPOLOGICAL QUIVERS

open access: yesInternational Journal of Mathematics, 2005
Topological quivers are generalizations of directed graphs in which the sets of vertices and edges are locally compact Hausdorff spaces. Associated to such a topological quiver [Formula: see text] is a C*-correspondence, and from this correspondence one may construct a Cuntz–Pimsner algebra [Formula: see text].

ICrAData - Software for InterCriteria Analysis [PDF]

open access: yesInternational Journal Bioautomation, 2018
In this paper, we consider the InterCriteria Analysis (ICrA), which is based on the index matrices and intuitionistic fuzzy sets. We demonstrate the application of ICrA using the software ICrAData.

𝜅-topologies for right topological semigroups [PDF]

open access: yesProceedings of the American Mathematical Society, 1992
Given a cardinal κ \kappa and a right topological semigroup S S with topology τ \tau , we consider the new topology obtained by declaring any intersection of at most κ \kappa members of τ \tau to be open.
