does it solve this one?

============

kernelopts(version);

Maple V, Release 5.1, IBM INTEL NT, Nov 05 1998, WIN-5510-980921-1

h(t):=(log(1/t))^(-b);

pdsolve(-a*u(t,x)+diff(u(t,x),t)+c*h(t)*diff(h(t),t)*diff(u(t,x),x,x)=0,u(t,x),build);

Thank you,

Thank you,

Vilen

wow ... hmm

Alec, thank you so much

I am getting

> pdsolve(-a*u(t,x)+diff(u(t,x),t)+b*diff(u(t,x),x,x)=0,u(t,x));

                                        / 2         \
                       /d         \     |d          |
  pdsolve(-a u(t, x) + |-- u(t, x)| + b |--- u(t, x)| = 0, u(t, x))
                       \dt        /     |  2        |
                                        \dx         /

maybe I am missing some of the components, btw I am running it in Maple V

Could you try running

=====================================

> h(t):=(log(1/t))^(-b);

                                        (-b)
                         h(t) := ln(1/t)

> pdesolve(-a*u(t,x)+diff(u(t,x),t)+c*h(t)*diff(h(t),t)*diff(u(t,x),x,x)=0,u(t,x));
=====================================

Do you get any solutions for this one?

Thanx,
