Frequently Hypercyclic and Chaotic Behavior of Some First-Order Partial Differential Equation

open access: yesAbstract and Applied Analysis, 2013
We study a particular first-order partial differential equation which arisen from a biologic model. We found that the solution semigroup of this partial differential equation is a frequently hypercyclic semigroup.

Fractal First-Order Partial Differential Equations [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2006
The present paper is concerned with semilinear partial differential equations involving a particular pseudo-differential operator. It investigates both fractal conservation laws and non-local Hamilton-Jacobi equations. The starting point is a new formula for the operator.

Maillet type theorem for singular first order nonlinear partial differential equations of totally characteristic type. Part II [PDF]

open access: yesOpuscula Mathematica, 2015
In this paper, we study the following nonlinear first order partial differential equation: \[f(t,x,u,\partial_t u,\partial_x u)=0\quad\text{with}\quad u(0,x)\equiv 0.\] The purpose of this paper is to determine the estimate of Gevrey order under the ...
