Down-step statistics in generalized Dyck paths [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2022
The number of down-steps between pairs of up-steps in $k_t$-Dyck paths, a generalization of Dyck paths consisting of steps $\{(1, k), (1, -1)\}$ such that the path stays (weakly) above the line $y=-t$, is studied.

Postulates of the cognitive theory of thinking and their consequences [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2022
Purpose of the work is to create a theoretical model of the thinking process, considered as a set of operations for the formation of cognitive generalizations of the level of categories (concepts).

Teaching Combinatorial Principles Using Relations through the Placemat Method

open access: yesMathematics, 2021
The presented paper is devoted to an innovative way of teaching mathematics, specifically the subject combinatorics in high schools. This is because combinatorics is closely connected with the beginnings of informatics and several other scientific ...

Some identities on degenerate poly-Euler polynomials arising from degenerate polylogarithm functions

open access: yesApplied Mathematics in Science and Engineering, 2023
Our main focus here is a new type of degenerate poly-Euler polynomials and numbers. This focus stems from their nascent importance for applications in combinatorics, number theory and in other aspects of applied mathematics.

On problems concerning fixed-point-free permutations and on the polycirculant conjecture-a survey [PDF]

open access: yesTransactions on Combinatorics, 2019
Fixed-point-free permutations‎, ‎also known as derangements‎, ‎have been studied for centuries‎. ‎In particular‎, ‎depending on their applications‎, ‎derangements of prime-power order and of prime order have always played a crucial role in a variety of ...

A Topological Perspective on Interacting Algebraic Theories [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
Techniques from higher categories and higher-dimensional rewriting are becoming increasingly important for understanding the finer, computational properties of higher algebraic theories that arise, among other fields, in quantum computation.

Spectral recognition of graphs [PDF]

open access: yesYugoslav Journal of Operations Research, 2012
At some time, in the childhood of spectral graph theory, it was conjectured that non-isomorphic graphs have different spectra, i.e. that graphs are characterized by their spectra.

Frequency-Dependent Competition Between Strains Imparts Persistence to Perturbations in a Model of Plasmodium falciparum Malaria Transmission

open access: yesFrontiers in Ecology and Evolution, 2021
In high-transmission endemic regions, local populations of Plasmodium falciparum exhibit vast diversity of the var genes encoding its major surface antigen, with each parasite comprising multiple copies from this diverse gene pool. This strategy to evade
