Elementary groups in $\PSL(3,\C)$
Waldemar Barrera, Angel Cano, Juan Pablo Navarrete +1
In this paper, we give a classification of the subgroups of that act on in such a way that their Kulkarni limit set has fi…
Egerváry's theorems for harmonic trinomials
Gerardo Barrera, Waldemar Barrera, Juan Pablo Navarrete
In this manuscript, we study the arrangements of the roots in the complex plane for the lacunary harmonic polynomials called harmonic trinomials. We provide necessary and sufficien…
Action of -Fuchsian groups on
W. Barrera, E. Montiel, J. P. Navarrete
We consider discrete subgroups of the group of orientation preserving isometries of the -dimensional hyperbolic space, whose limit set is a -dimensional real sphere, acti…
The stability region for Schur stable trinomials with general complex coefficients
Gerardo Barrera, Waldemar Barrera, Juan Pablo Navarrete
In this paper, we characterize the stability region for trinomials of the form , , where , and are non-zero complex numbers and $n…
On the space of compact diamonds of Lorentzian length spaces
Waldemar Barrera, Luis Montes de Oca, Didier A. Solis
In this work we introduce the taxicab and uniform products for Lorentzian pre-length spaces. We further use these concepts to endow the space of causal diamonds wi…
