| Abstract: | In this paper,weighted estimation of generalized second spectrum for a kind of differential system is considered.The inequality of the upper bound of second spectrum is estimated from the first spectrum by using spectrum theory of operator,matrix operation,integration by parts,generalized Rayleigh theorem and Schwartz inequality etc.The estimate coefficients are independent to the measure of the domain in which the problem is concerned.The result is significant in the research field of spectrum estimation of differential equations. |
