Prospects of “topologically unquenched QCD” from a study of the analogous importance sampling method in the massive Schwinger model [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2000
I give a quick summary of my proposal for simulating an improvement on quenched QCD with dynamical fermions which interact with the gluon configuration only via the topological index of the latter. It amounts to include only the topological part of the functional determinant into the measure, thereby absorbing a correction factor into the observable. I

Equivalence of K-functionals and modulus of smoothness generated by a Dunkl type operator on the interval $(-1, 1)$

open access: yesComptes Rendus. Mathématique, 2023
Our aim in this paper is to show that the modulus of smoothness and the $K$-functionals constructed from the Sobolev-type space corresponding to the Dunkl operator are equivalent on the interval $(-1,1)$.

Bombay hypertopologies

open access: yesApplied General Topology, 2003
Recently it was shown that, in a metric space, the upper Wijsman convergence can be topologized with the introduction of a new far-miss topology. The resulting Wijsman topology is a mixture of the ball topology and the proximal ball topology.

New light on Bergman complexes by decomposing matroid types [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
Bergman complexes are polyhedral complexes associated to matroids. Faces of these complexes are certain matroids, called matroid types, too. In order to understand the structure of these faces we decompose matroid types into direct summands.

Graph topologies on closed multifunctions

open access: yesApplied General Topology, 2003
In this paper we study function space topologies on closed multifunctions, i.e. closed relations on X x Y using various hypertopologies. The hypertopologies are in essence, graph topologies i.e topologies on functions considered as graphs which are ...

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 ...

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.

Asymptotic topology [PDF]

open access: yes, 1999
We establish some basic theorems in dimension theory and absolute extensor theory in the coarse category of metric spaces. Some of the statements in this category can be translated in general topology language by applying the Higson corona functor.

The order topology for a von Neumann algebra [PDF]

open access: yes, 2014
The order topology $\tau_o(P)$ (resp. the sequential order topology $\tau_{os}(P)$) on a poset $P$ is the topology that has as its closed sets those that contain the order limits of all their order convergent nets (resp. sequences).
