    Rigorous numerics for nonlinear heat equations in the complex plane of time

    In this paper, we introduce a method for computing rigorous local inclusions of solutions of Cauchy problems for nonlinear heat equations for complex time values. The proof is constructive and provides explici...

    Numerical validation of blow-up solutions with quasi-homogeneous compactifications

    We provide a numerical validation method of blow-up solutions for finite dimensional vector fields admitting asymptotic quasi-homogeneity at infinity. Our methodology is based on quasi-homogeneous compactifica...
