Blow-Up of Solutions to a Generalized Tricomi Equation with?a Nonlinear Memory Term of Derivative Type

OUYANG Baiping*

Abstract：In this research blow-up of solutions to a generalized Tricomi equation with a nonlinear memory term of derivative type is considered. By introducing time-dependent functionals and modified Bessel equations， an iterative frame and the first lower bound of solutions are derived. Then， application of iteration methods leads to proof of the nonexistence of global solutions and an upper bound estimate of solutions for the lifespan in subcritical case. Meanwhile， the nonlocal influence from the nonlinear memory term of derivative type on the solution of generalized Tricomi equation is obtained.

Key words：nonlinear memory term of derivative type; generalized Tricomi equation; blow-up; lifespan
