I have a problem with DSolve
and the following code:
DSolve[{D[\[CapitalPsi][x]D[Ψ[x], x, x] == \[Kappa]^2κ^2 \[CapitalPsi][x]Ψ[x],
\[CapitalPsi][0]Ψ[0] == \[CapitalPsi]sΨs, \[CapitalPsi][Infinity]Ψ[Infinity] == 0}, \[CapitalPsi]Ψ, x]
The error getting displayed in Mathematica is: DSolve::bvlim: For some branches of the general solution, unable to compute the limit at the given points. Some of the solutions may be lost.
DSolve::bvlim: For some branches of the general solution, unable to
compute the limit at the given points. Some of the solutions may be lost.
