Near as I can figure out the function p(k,t) represents for a
particular
time t0 how strongly the function p(x,t0) = f(x) is like exp(ikx).
If f(x) is alot like exp(ikx) then |f(k)| will have a high value. If
f(x) is exactly like exp(ikx) then |f(k)| will be infinite. If it is
not
alike at all then the value will be 0. Alike has to do with what
frequency
f(x) modulates with compared to exp(ikx). I am using the fourier
transform

p[k,t] := Integrate[p[x,t] exp[-ikx], {x, -Infinity, Infinity}]

If you are using a different transform I hope you can translate the
meaning
accordingly. The notation above is Mathamaticaese...
