Applications of Supersymmetric Polynomials in Statistical Quantum Physics
I Chernega, M Martsinkiv, T Vasylyshyn… - Quantum …, 2023 - mdpi.com
We propose a correspondence between the partition functions of ideal gases consisting of
both bosons and fermions and the algebraic bases of supersymmetric polynomials on the …

Cauchy convergence in V-normed categories
Building on the notion of normed category as suggested by Lawvere, we introduce notions
of Cauchy convergence and cocompleteness which differ from proposals in previous works …

Haar- sets: looking at small sets in Polish groups through compact glasses
T Banakh, S Głąb, E Jabłońska, J Swaczyna - arXiv preprint arXiv …, 2018 - arxiv.org
Generalizing Christensen's notion of a Haar-null set and Darji's notion of a Haar-meager set,
we introduce and study the notion of a Haar-$\mathcal I $ set in a Polish group. Here …

Continuity in right semitopological groups
E Reznichenko - arXiv preprint arXiv:2205.06316, 2022 - arxiv.org
Groups with a topology that is in consistent one way or another with the algebraic structure
are considered. Classical groups with a topology are topological, paratopological …

[HTML][HTML] Additivity, subadditivity and linearity: automatic continuity and quantifier weakening
NH Bingham, AJ Ostaszewski - Indagationes Mathematicae, 2018 - Elsevier
We study the interplay between additivity (as in the Cauchy functional equation),
subadditivity and linearity. We obtain automatic continuity results in which additive or …

[HTML][HTML] Beyond Lebesgue and Baire IV: density topologies and a converse Steinhaus–Weil theorem
NH Bingham, AJ Ostaszewski - Topology and its Applications, 2018 - Elsevier
The theme here is category-measure duality, in the context of a topological group. One can
often handle the (Baire) category case and the (Lebesgue, or Haar) measure cases …

Beurling slow and regular variation
NH Bingham, AJ Ostaszewski - Transactions of the London …, 2014 - academic.oup.com
We give a new theory of Beurling regular variation (Part II). This includes the previously
known theory of Beurling slow variation (Part I) to which we contribute by extending Bloom's …

Midconvex sets in Abelian groups
A subset $ X $ of an Abelian group $ G $ is called $ midconvex $ if for every $ x, y\in X $ the
set $\frac {x+ y} 2=\{z\in G: 2z= x+ y\} $ is a subset of $ X $. We prove that a subset $ X $ of …

Lipschitz perturbations of expansive systems
A Artigue - arXiv preprint arXiv:1405.7401, 2014 - arxiv.org
We extend some known results from smooth dynamical systems to the category of Lipschitz
homeomorphisms of compact metric spaces. We consider dynamical properties as robust …

Group action and shift-compactness
HI Miller, AJ Ostaszewski - Journal of Mathematical Analysis and …, 2012 - Elsevier
Shift-compactness has recently been found to be the foundation stone of classical, as well
as topological, regular variation; most recently it has come again to prominence in new …
