%0 Journal Article %T Integral equalities for functions of unbounded spectral operators in Banach spaces %A Benedetto Silvestri %J Mathematics %D 2008 %I arXiv %R 10.4064/dm464-0-1 %X We investigate a limiting procedure for extending local integral operator equalities to the global ones and to applying it to obtaining generalizations of the Newton-Leibnitz formula for operator-valued maps for a wide class of unbounded operators. %U http://arxiv.org/abs/0804.3069v3
