On blowing-up solutions for multi–time nonlinear hyperbolic equations and systems


B Ahmad, A Alsaedi, E Cuesta, M Kirane




For a two–dimensional time nonlinear hyperbolic equation with a power nonlinearity, a threshold exponent depending on the space dimension is presented. Furthermore, the analysis is extended not only to a system of two equations but also to a two–time fractional nonlinear equation with different time order derivatives.
