In these notes we provide an introduction to compact linear operators on Banach and Hilbert spaces. These operators behave very much like familiar finite dimensional matrices, without necessarily having finite rank. For more thorough treatments, see [RS, Y]. Definition 1 Let X and Y be Banach spaces. A linear operator C : X → Y is said to be compact if for each bounded sequence {xi}i∈IN ⊂ X , t...

El Bronce de Ascoli no sólo es la primera prueba documental concesión ciudadanía romana a un grupo provinciales, sino que también muestra relación gens Pompeia con Hispania, específicamente en el valle del Ebro, región donde se reclutó esta unidad militar.

Abstract In this paper we estimate the Kuratowski and Hausdorff measures of noncompactness bounded subsets spaces vector-valued functions differentiable functions. To end, use a quantitative characteristic modeled on new equicontinuity-type concept classical characteristics related to pointwise relative compactness. We obtain regular in taken into consideration. The established inequalities red...

The kinetics of CO binding to the horse myoglobin fragment Mb-(32-139), the so-called "mini-Mb," were investigated by laser flash photolysis in 0.1 M phosphate buffer and in buffer with 75% (vol/vol) glycerol. The reaction displays complex time courses that can be approximated satisfactorily only with a sum of five exponentials. The features of the kinetic components and a comparison of the deo...
