Nested cases, alignment and numbering
6
I have tried all different sorts of solutions including align, aligned, cases and equation to have the result I get with this code except that I want numbering for the three lines in the aligned subenvironment. Do you have a solution or better way of representing this?
begin{equation}
left{
begin{aligned}
partial_t u(vec{x},t) - alpha Delta u(vec{x},t) &= f(vec{x}), &&(vec{x},t) in Omega times J, \
%
u(vec{x},t) &= 0, &&(vec{x},t) in partial Omega times J, \
%
u(vec{x},0) &=
begin{cases}
rho, &vec{x} in T \
0, &vec{x} in B textbackslash T
end{cases}
&&vec{x} in B
end{aligned}
right.

@RobinHellmers -textbackslashis a text-mode command. In contrast,setminusis a math-mode command. In your screenshot, note that the spacing around the backslash character is too tight, when compared to the screenshots posted by Zarko and myself.
