Bifurcation of a Leslie–Gower Predator–Prey Model with Nonlinear Harvesting and a Generalist Predator

open access: yesAxioms
A Leslie–Gower predator–prey model with nonlinear harvesting and a generalist predator is considered in this paper. It is shown that the degenerate positive equilibrium of the system is a cusp of codimension up to 4, and the system admits the cusp-type ...

On expanding attractors of arbitrary codimension

open access: yesСовременная математика: Фундаментальные направления
Thanks to the works by R.V. Plykin and V.Z. Grines, the most studied expanding attractors are orientable attractors of codimension one of A -diffeomorphisms of multidimensional closed manifolds and one-dimensional attractors on closed surfaces.

Higher-order Nielsen numbers

open access: yesFixed Point Theory and Applications, 2005
Suppose X, Y are manifolds, f,g:X→Y are maps. The well-known coincidence problem studies the coincidence set C={x:f(x)=g(x)}. The number m=dim X−dim Y is called the codimension of the problem. More general is the preimage problem. For
