pdesolve in Maple V

Hey guys,

I am struggling again trying to solve very similar pde in Maple V.

pdesolve(-a*u(t,x)+diff(u(t,x),t)+(c^2)*b*(1/t)*[log(2*T/t)]^(-b-1)diff(u(t,x),x,x)=0,u(t,x))

Could anybody try running it in the older version? Are there any solutions?

Thank you,

Vilen

Something is missing

Is there a multiplication (or other) sign in front of the last diff?

missed multiplicaion sign, still no results in Maple V

pdesolve(-a*u(t,x)+diff(u(t,x),t)+(c^2)*b*(1/t)*[[log(2*T/t)]^(-b-1)]*diff(u(t,x),x,x)=0,u(t,x))

Thanx

I think you want this syntax:

pdsolve(-a*u(t,x)+diff(u(t,x),t)+(c^2)*b*(1/t)*((ln(2*T/t))^(-b-1))*diff(u(t,x),x,x)=0,u(t,x));

Note that log is ln, and there are no square brackets.
