Global planar dynamics with a star node and contracting nolinearity

Begoña Alarcón, Sofia B. S. D. Castro, Isabel S. Labouriau

This is a complete study of the dynamics of polynomial planar vector fields whose linear part is a multiple of the identity and whose nonlinear part is a contracting homogeneous po…

Stability of cycles and survival in a Jungle Game with four species

Sofia B. S. D. Castro, Ana M. J. Ferreira, Isabel S. Labouriau

The Jungle Game is used in population dynamics to describe cyclic competition among species that interact via a food chain. The dynamics of the Jungle Game supports a heteroclinic…

Learning coordination through new actions

Sofia B. S. D. Castro

We provide a novel approach to achieving a desired outcome in a coordination game: the original 2x2 game is embedded in a 2x3 game where one of the players may use a third action.…

Arbitrarily large heteroclinic networks in fixed low-dimensional state space

Sofia B. S. D. Castro, Alexander Lohse

We consider heteroclinic networks between nodes where the only connections are those linking each node to its two subsequent neighbouring ones. Using a construct…

Stability of cycles in a game of Rock-Scissors-Paper-Lizard-Spock

Sofia B. S. D. Castro, Liliana Garrido-da-Silva, Ana Ferreira +1

We study a system of ordinary differential equations in R5 that is used as a model both in population dynamics and in game theory, and is known to exhibit a heteroclinic network co…

Qualitative planar dynamics with star nodes and homogeneous nonlinearities: beyond Hilbert's problem

Begoña Alarcón, Sofia B. S. D. Castro, Isabel S. Labouriau

This is a full study of the dynamics of polynomial planar vector fields whose linear part is a multiple of the identity and whose nonlinear part is a homogeneous polynomial of arbi…
