I am a absolute novice in Mathematica and I am trying to solve the following system of PDE: 0.5 sigv^2 z[t]^2 + z[t] (rho sigv phi I - b) -0.5 phi^2 + u phi I + D[z[t],t]=0 z[0]=0 I would like to know, what z[t, rho, sigv, phi, u, b] is and so I typed into Mathematica the following: <<calculus`PDSolve1` DSolve[{0.5 sigv^2 z[t]^2 + z[t] (rho sigv phi I - b) -0.5 phi^2 + u phi I + D[z[t],t]==0, z[0]==0}, z[t],{t}] Unfortunately the result doesn`t look like I expected it to be. I think the result given by Mathematica is to complicated. What did I do wrong? Could anybody help me? Claus Campenhausen at SGCL1.UNISG.CH
