On a class of predator-prey models of Gause type with Allee effect and a square-root functional response

Puchuri, Liliana; Bueno, Orestes (Pontificia Universidad Católica del PerúPE, 2022-08-31)

A predator-prey model of Gause type is an extension of the classical Lotka-Volterra predator-prey model. In this work, we study a predator-prey model of Gause type, where the prey growth rate is subject to an Allee effect ...
Hyperbolic groups with few linear representations

Vargas Pallete, Franco (Pontificia Universidad Católica del PerúPE, 2022-08-31)

In this paper we are going to develop an unpublished argument of William Thurston that shows the existence of hyperbolic groups with no non-trivial representations to linear groups over any ring, for a given dimension. His ...
A remark on the Tjurina and Milnor numbers of a foliation of second type

Fernández Sánchez, Percy; García, Evelia R.; Saravia Molina, Nancy (Pontificia Universidad Católica del PerúPE, 2022-08-31)

We present a relation between the Tjurina and Milnor numbers of a holomorphic foliation of secont type and the Tjurina and Milnor numbers of its union of separatrices when this last one is holomorphic.
