Electron. J. Differ. Equ. 2002, 155-165, electronic only (2002)

Summary

Summary: We prove instantaneous blow-up of nonnegative solutions for a class of semilinear hyperbolic inequalities with first order terms and singular coefficients. The present approach relies on a suitable choice of the functions used to test the differential inequalities.
