What exactly is an eigenvalue?
"To be an eigenfunction, the operator has to reproduce the function with some multiplicative constant."
Is the eigenvalue the multiplicative constant or is it the m constant and the function?
Many thanks.

I'll also like to thank Dr. Physics for helping me last time :)

The eigenvalue is the scalar multiplying value. Yes, DrPhysics is a very well known person in the field of physics, and it is a pleasure to have known him, and worked with him, for the past sixteen years. I will relay your thanks.
