Strong summability of double series by matrix methods and Tauberian theorems for these methods

Mathematical Notes of the Academy of Sciences of the USSR, 1975
Conditions are established under which matrix transformations of double series and sequences preserve strong convergence. In addition, a general Tauberian theorem is established and applied to the method of Borel.

Praca jest streszczeniem opartym głównie na mojej pracy doktorskiej z uwzględnieniem pewnych modyfikacji i uzupełnień. Na początku, po omówieniu ogólnego pojęcia metody w sensie teorii sumowalności, wprowadzono pojęcie ciągowej metody macierzowej (sequential matrix method, SM-method).
