Convolution of a harmonic mapping with $n$-starlike mappings and its partial sums [PDF]

arXiv, 2017
We investigate the univalency and the directional convexity of the convolution $\phi\tilde{*}f=\phi*h+\overline{\phi*g}$ of the harmonic mapping $f=h+\bar{g}$ with a mapping $\phi$ whose convolution with the mapping $z+\sum_{k=2}^{\infty}k^nz^k$ is starlike (and such a mapping $\phi$ is called $n$-starlike).

A Class of Linear Positive Maps in Matrix Algebras [PDF]

arXiv, 2003
A class of linear positive, trace preserving maps in $M_n$ is given in terms of affine maps in $\bBR^{n^2-1}$ which map the closed unit ball into itself.

Real divergence-free Jacobian maps are shear maps [PDF]

arXiv, 2009
We show that divergence-free jacobian maps, recently considered in \cite{N}, \cite{S}, are actually shear maps.

On the topology of stable maps [PDF]

arXiv, 2010
We investigate how Viro's integral calculus applies for the study of the topology of stable maps. We also discuss several applications to Morin maps and complex maps.

Perturbations of flexible Lattès maps [PDF]

arXiv, 2011
We prove that any Latt\`es map can be approximated by strictly postcritically finite rational maps which are not Latt\`es maps.

On Lie n-centralizers, n-commuting linear maps and related mappings [PDF]

arXiv
In this article, we consider several local conditions under which linear mappings on algebras act like Lie n-centralizers and we study these linear mappings, Lie n-centralizers and n-commuting linear maps.
