Control theory for degenerate parabolic and wave equations has emerged as a vibrant field that combines deep theoretical insights with practical applications across physics and engineering. Such ...

Control and inverse problems in wave equations and graphs constitute a dynamic field at the intersection of applied mathematics, engineering and physics. This area investigates how waves propagating ...

Beijing Zhongke Journal Publising Co. Ltd. The study of large-time behavior of solutions to partial differential equations is a fundamental pursuit in mathematical analysis, with profound implications ...

We consider the wave equations with perturbation of the first order differential operators, the coefficients of which depend on both the space and time variables. Under suitable conditions on the ...
