How Do Eigenfunctions Behave in a Triple Delta Potential Well System?

one at -a, 0, and a.
Eigenfunctions?

 

[Meir Achuz]

Assuming the deltas are all positive,
te efs are cosh between the deltas, and exponential beyond.
The BC is that the difference in slopes at -a, 0, +a is V if the pots are
V\delta(0), etc.
