Digraph Groups Without Leaf Having An Arc Count One Greater Than Their Vertex
Cumhuriyet Science JournalThis paper investigates a particular class of digraph groups that are defined by non-empty balanced presentations. Each relation is expressed in the form R(x,y), where x and y are distinct generators, and R(⋅,⋅) is based on a fixed cyclically reduced ...

On the Existence of the Solutions for Some Nonlinear Volterra Integral Equations
Abstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013 We present a theorem which gives sufficient conditions for existence of at least one solution for some nonlinear functional integral equations in the space of continuous functions on the interval [0,a]. To do this, we will use Darbo′s fixed‐point theorem associated with the measure of noncompactness. We give also an example satisfying the conditions of

Minimum‐degree conditions for rainbow triangles
Journal of Graph Theory, Volume 107, Issue 2, Page 298-329, October 2024.Abstract Let G ≔( G 1 , G 2 , G 3 ) ${\bf{G}}:= ({G}_{1},{G}_{2},{G}_{3})$ be a triple of graphs on a common vertex set V $V$ of size n $n$. A rainbow triangle in G ${\bf{G}}$ is a triple of edges (e 1 , e 2 , e 3 ) $({e}_{1},{e}_{2},{e}_{3})$ with e i ∈ G i ${e}_{i}\in {G}_{i}$ for each i $i$ and {e 1 , e 2 , e 3 } $\{{e}_{1},{e}_{2},{e}_{3 ...

First‐Order Three‐Point Boundary Value Problems at Resonance Part III
Journal of Applied Mathematics, Volume 2012, Issue 1, 2012., 2012 The main purpose of this paper is to investigate the existence of solutions of BVPs for a very general case in which both the system of ordinary differential equations and the boundary conditions are nonlinear. By employing the implicit function theorem, sufficient conditions for the existence of three‐point boundary value problems are established.

Fast mvSLOUCH: Multivariate Ornstein–Uhlenbeck‐based models of trait evolution on large phylogenies
Methods in Ecology and Evolution, Volume 15, Issue 9, Page 1507-1515, September 2024.Abstract The PCMBase R package is a powerful computational tool that enables efficient calculations of likelihoods for a wide range of phylogenetic Gaussian models. Taking advantage of it, we redesigned the R package mvSLOUCH. Here, we demonstrate how the new version of the package can be used to thoroughly examine the evolution and adaptation of ...
