Generalized Gaussian Estimates and Local Limit Theorems for Discrete Convolution Powers of Complex Functions: The -dimensional case
Pedro H. Alves, Evan Randles, José M. Valdovinos
We establish generalized Gaussian estimates and local limit theorems with cumulants, up to any order of accuracy, with sharp Gaussian-type error for the convolution powers of certa…

Dissipative structure of higher order regularizations of hyperbolic systems of conservation laws in several space dimensions
Felipe Angeles, Ramón G. Plaza, José Manuel Valdovinos
This work studies the dissipative structure of regularizations of any order of hyperbolic systems of conservation laws in several space dimensions. It is proved that the seminal eq…
