Ítem Estimación de la norma de operadores matriciales actuando entre retículos de Banach de sucesionesDuque Orozco, Angie; Ramos Fernández, Julio CésarIn this work, the norm of operators defined by infinite matrices between Banach lattices will be estimated, more specifically on the spaces l^1 and l^2, where, for the case of the space l^1, it is possible to determine exactly the norm of the operator, while that when addressing the l^2 space, a study of a result was carried out due to Mastylo and Mleczko [13], as well as the Schur test in order to lower and upper limit the norm of these operators defined in l^2, providing additionally a criterion to determine when the operator will act on l^2 is bounded.
