Abstract: | We obtain Taylor approximations for functionals V?Tr(f(H0+V)) defined on the bounded self-adjoint operators, where H0 is a self-adjoint operator with compact resolvent and f is a sufficiently nice scalar function, relaxing assumptions on the operators made in 17], and derive estimates and representations for the remainders of these approximations. |
