DESCRIPTION:The first our aim is to clarify the results obtained by Lidskii V.B. devoted to the decomposition on the root vector system of a non-selfadjoint compact operator. We use a technique of the entire function theory and introduce a so-called Schatten-von Neumann class of the convergence exponent. Considering strictly accretive operators satisfying special conditions formulated in terms of the norm\, we construct a sequence of contours of the power type on the contrary to the results by Lidskii V.B.\, where a sequence of contours of the exponential type was used. This approach allows us to obtain a decomposition on the root vector series of the non-selfadjoint operators with the s-number asymptotics more subtle than one of the power type.
