Solve the following initial value problem for u(x, ) on a semi-infinite interval, using a Greens
Question:
Solve the following initial value problem for u(x, τ ) on a semi-infinite interval, using a Green’s function:
with
u(x, 0) = u0(x) for x > 0, u(0, τ ) = 0 for τ > 0.
Define v(x, τ) as
v(x, τ ) = u(x, τ) if x > 0,
v(x, τ ) = −u(−x, τ) if x < 0.
Then we can show that v(0, τ ) = 0 and
