Помогите пожалуйста решить задачу и если можно с комментариями, дабы понять как это решается.
Задание: Решить краевую задачу:
du / dt = a^2 * ((d^2)u / d(x^2)) 0<x, t<+infinity u| =U(нулевое) u| =0
|x=0 |t=0

Я правильно написал?
du/dt = a2(d2u/dx2)
x > 0, t < +[$8734$], u(x=0) = U0, u(t=0) = 0

Что-то не так с граничными условиями.
При x=0 u=U0 , при t=0 u=0,
или U0 =0 ?
