HYPERBOLIC QUENCHING PROBLEM WITH DAMPING IN THE MICRO-ELECTRO MECHANICAL SYSTEM DEVICE

摘要

We study the initial boundary value problem for the damped hyperbolic equation arising in the micro-electro mechanical system device with local or nonlocal singular nonlinearity. For both cases, we provide some criteria for quenching and global existence of the solution. We also derive the existence of the quenching curve for the corresponding Cauchy problem with local source.
