In the special case where D is defined on a function space, the eigenvectors are referred to as eigenfunctions. That is, a function f is an eigenfunction of D if it satisfies the equation cheap yiwu christmas market

"WebThe spherical harmonic functions are chosen to be eigenfunctions of Lz rather than Lx or Ly to honour Zaccharias Hermite, the inventor of the Hermitian operators. just by convention. Lx,Ly and Lz all commute with each other anyway. because x and y are indistinguishable. Only z is a well-defined coordinate. just by convention. " - Eigenfunctions of lx
