Question

what is eigen function in chemistry ​

Answer 1

Answer:

Such an equation, where the operator, operating on a function, produces a constant times the function, is called an eigenvalue equation. The function is called an eigenfunction, and the resulting numerical value is called the eigenvalue. Eigen here is the German word meaning self or own.

Answer 2

Answer:

If an operator  operates on a well-behaved function to give the same function by multiplying with the constant, then that function is called "Eigen Function" and that multiple constant is called as "Eigen Value”. Let be the function and 'a' is a constant multiplying factor.
