Higher Order Structure along Nilpotent Eigendirections in Planar Vector Fields

Roberto Albarran-García, Martha Alvarez Ramírez, Marco Polo García-Rivera

We study a distinguished one dimensional restriction associated with planar vector fields whose linearization is a nonzero nilpotent matrix of index two. This restriction admits an…

An exact structural identity and its normal form consequences in a modified Leslie--Gower model

Roberto Albarrán-García, Martha Alvarez-Ramírez, Marco Polo García-Rivera

Zhao and Zhao (2026) established a codimension-four Bogdanov--Takens singularity in a modified Leslie--Gower predator--prey model through a recursive normal form computation. We sh…

Endogenous Cycles in a Keen--Goodwin Model with Minsky Debt

Roberto Albarrán-García, Martha Alvarez-Ramírez, Carlos García-Azpeitia

We analyze a three-dimensional Keen--Goodwin model that couples wage--employment dynamics with Minsky-style private debt. At zero real interest the interior equilibrium is nonhyper…
