Abstract

In the present paper an operator-differential equation of second order in complex domain is
considered when the coefficients have singularity of pole type at the point z=0. A theorem of existence of the
solution of the equation is proved and the spectral property of the solution is separately investigated when the
coefficients are spectral operators.
