Abstract:
The following problem uu=αuxx-uxxu=φ(ux)x,u(x,0)=u0(x),ui(x,0)=u1(x),where α〉 0 and φ(s) is a nonlinear function is discussed. The local solution and the global solution of the Cauchy problem ( 1 ), (2) are discussed. By using the concavity method, the blow-up of the solution of this problem when the φ(s) satisfies some conditions is studied.[著者文摘]
Key words:
