We use a technique of the entire function theory and introduce a so-called Schatten-von Neumann class of the convergent exponent. Considering strictly accretive operators satisfying special conditions formulated in terms of the norm, we construct a sequence of contours of the power type in the contrary to the results of Lidsky V.B., where a exponential type sequence of contours was used.", "revisions": [ { "version": "v2", "updated": "2022-02-13T05:31:04.000Z" } ], "analyses": { "subjects": [ "47B28", "47A10", "47B12", "47B10", "47B25", "20M05", "26A33" ], "keywords": [ "schatten-von neumann class", "natural lacunae method", "convergence exponent", "operators satisfying special conditions", "accretive operators satisfying special" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
