Resolution of singularities of 2-dimensional real analytic constrained differential systems

Otavio Henrique Perez, Paulo Ricardo da Silva

We present a theorem of resolution of singularities for real analytic constrained differential systems $A (x) x ˙ = F (x)$ defined on a 2-manifold with corners having impasse set…

Phase Portrait of the Riccati Quadratic Polynomial Differential Systems

Jaume Llibre, Bruno Dominiciano Lopes, Paulo Ricardo da Silva

In this paper we characterize the phase portrait of the Riccati quadratic polynomial differential systems $x ˙ = α_{2} (x), y ˙ = k y^{2} + β_{1} (x) y + γ_{2} (x),$ with $(x,y)\in…
