Lviv period for Smoluchowski: Science, teaching, and beyond
A. Rovenchak
A major part of Marian Smoluchowski's achievements in science corresponds to the period of his work at the University of Lviv. Since this part is well described in the literature,…
Matrix generalizations of integrable systems with Lax integro-differential representations
Oleksandr Chvartatskyi, Yuriy Sydorenko
We present (2+1)-dimensional generalizations of the k-constrained Kadomtsev-Petviashvili (k-cKP) hierarchy and corresponding matrix Lax representations that consist of two integro-…
Classification Analysis Of Authorship Fiction Texts in The Space Of Semantic Fields
Bohdan Pavlyshenko
The use of naive Bayesian classifier (NB) and the classifier by the k nearest neighbors (kNN) in classification semantic analysis of authors' texts of English fiction has been anal…
On the compressibility of deformable spin chains in a vicinity of quantum critical points
Oleg Derzhko, Jozef Strecka, Lucia Galisova
We calculate the ground-state compressibility of a deformable spin-1/2 Heisenberg-Ising chain with Dzyaloshinskii-Moriya interaction to discuss how a quantum critical point inheren…
On monoids of monotone injective partial self-maps of integers with cofinite domains and images
Oleg Gutik, Dušan Repovš
We study the semigroup of monotone injective partial selfmaps of the set of integers having cofinite domain and image. We show that $\…
Semiquantitative theory for high-field low-temperature properties of a distorted diamond spin chain
Oleg Derzhko, Johannes Richter, Olesia Krupnitska
We consider the antiferromagnetic Heisenberg model on a distorted diamond chain and use the localized-magnon picture adapted to a distorted geometry to discuss some of its high-fie…
