Definition of a Differential Eigenvalue Problem?

Click For Summary
SUMMARY

A Differential Eigenvalue Problem is defined by the equation \(\lambda y = L y\), where \(\lambda\) represents the eigenvalue and \(L\) is a linear operator acting on a function \(y\). In this context, an eigenfunction is a function that, when the operator \(L\) is applied, results in a constant multiple of itself, which is the eigenvalue. The term "differential" refers to the nature of the operator \(L\) being a differential operator, which involves derivatives of the function.

Homework Statement



I would like to know what the definition of a Differential Eigenvalue Problem is please?
I am a maths undergraduate.

Homework Equations



\lambda y = L y, where \lambda is eigenvalue, L is a linear operator.

The Attempt at a Solution



I have searched via google, encylopedia britanica, wikipedia but only have a vague understanding. If someone could help me define it that would be great.

Thank you. :smile:

You just defined it. If an operator acts on a function and returns a constant multiple of that function then the function is an 'eigenfunction' and the value of the multiple is 'eigenvalue'. That's really all there is to it.
 
Thanks a lot :).
 
But why "differential"? :redface:
