Weak Solution of the Singular Cauchy Problem of Euler-Poisson-Darboux Equation for n= 4
(2013)
We consider the singular Cauchy problem of Euler-Poisson-Darboux equation (EPD) of the form utt+ k t ut=∇ 2u u (x, 0)= f (x), ut (x, 0)= 0 where∇ 2 is the Laplacian operator in R n, n will refer to dimension and k a real ...
