ABSTRACT

Different physical phenomena can be represented in terms of nonlinear problems for partial differential equations, however such problems are often subjected to singularities. Thus it gives rise to a permanent research interest to such problems. In the present study we provide reviews of essential approach applied to Cauchy problems and initial-boundary problems for hyperbolic equations based on latest results in this field. Also in this research we investigate the following problem    utt +ut −uxx = F(u), u(x,0) = x 3 , ut(x,0) = g(x). Where we prove the existence of unique solution (u) of the problem for 0 < t < φ, which blows up to +∞ as t → φ.
