Journal of Graph Theory, 2020 AbstractIf a graph has bounded clique number and sufficiently large chromatic number, what can we say about its induced subgraphs? András Gyárfás made a number of challenging conjectures about this in the early 1980s, which have remained open until recently; but in the last few years there has been substantial progress. This is a survey of where we are

Dynamics of General Class of Difference Equations and Population Model with Two Age Classes
Mathematics, 2020 In this paper, we study the qualitative behavior of solutions for a general class of difference equations. The criteria of local and global stability, boundedness and periodicity character (with period 2 k ) of the solution are established ...

A Dynamically Consistent Nonstandard Difference Scheme for a Discrete-Time Immunogenic Tumors Model
Entropy, 2022 This manuscript deals with the qualitative study of certain properties of an immunogenic tumors model. Mainly, we obtain a dynamically consistent discrete-time immunogenic tumors model using a nonstandard difference scheme.

Advanced Nonlinear Studies, 2020 We prove the validity of the ε-εβ{\varepsilon-\varepsilon^{\beta}} property in the isoperimetric problem with double density, generalising the known properties for the case of single density. As a consequence, we derive regularity for isoperimetric sets.

Two-Player Boundedness Counter Games [PDF]
, 2022 We consider two-player zero-sum games with winning objectives beyond regular languages, expressed as a parity condition in conjunction with a Boolean combination of boundedness conditions on a finite set of counters which can be incremented, reset to 0 ...

Dynamics of a host-pathogen model with constant mortality rate
Nonlinear Analysis, 2017 In this paper, we propose a discrete-time host-pathogen model and study its qualitative behavior. The model is for the spread of an infectious disease with constant mortality rate of hosts.

The Concept of Telicity in English, Romanian and Serbian
Romanian Journal of English Studies, 2020 Given that the notion of telicity was simply defined by English linguists as a situation which tends towards a goal, this paper will additionally explain and define telicity in the English language.
