Interpolation and Transmutation cover


We show that the existence of a transmutation between two self-adjoint operators L1L_{1} and L2L_{2} is equivalent to the existence of an interpolation operator in the spectral variable. This equivalence helps construct a transmutation operator between abstract self-adjoint operators.
