SUMMARY

The discussion focuses on the eigen functions of the linear operator L defined as L = -2i(∇f)·∇ - i∇²f + (∇f)², where f is an arbitrary function of x, y, and z. The operator incorporates the gradient and Laplacian of the function f, indicating a complex interplay between these mathematical constructs. Understanding the eigen functions of this operator is crucial for applications in quantum mechanics and differential equations.

Hi,
I am looking for eigen functions of the linear operator L defined by

[tex]L=(-2i(\nablaf).\nabla -i\nabla^2f +(\nablaf)^2)[/tex]

and here f is an abitary function of x,y,z

Sorry first (failed) attempt at latex.
L = -2i(grad(f)).grad -i(grad^2(f)) + (grad(f))^2

grad^2 is the laplacian of f
