A beam comes from - \infty to 0 and we have u(x) = e^(kx) + R e^(-kx) ; x<0. Why we omit the potential barrier when it comes to write the boundary. After the first term reaches in the box or well we write 0\geq x \leq 2a. When we take the limit when x goes to infinity shouldn't we omit the...

Hello there. I want to understand the mathematical idea behind boundaries that we write for a potential well. Why we use equally greater and smaller than let's say x between -4a and -2a but we only write x is less than -4a ? How to approach this idea with convergence theorem or Hilbert space...
