On relative Hausdorff measures of noncompactness and relative Chebyshev radii in Banach spaces [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1996
In this paper we prove some formulae and evaluations on relative Hausdorff measures of noncompactness and relative Chebyshev radii in various Banach spaces. We generalize the Lifschitz constant κ ( X ) \kappa (X) and introduce a function κ ~

Hausdorff Measures of Noncompactness and Interpolation Spaces [PDF]

open access: yes, 2006
2000 Mathematics Subject Classification: 46B50, 46B70, 46G12.A new measure of noncompactness on Banach spaces is defined from the Hausdorff measure of noncompactness, giving a quantitative version of a classical result by R. S. Phillips.

Decay mild solutions of the nonlocal Cauchy problem for second order evolution equations with memory [PDF]

open access: yes, 2016
Our aim in this paper is to find out decay mild solutions of the nonlocal Cauchy problem for a class of second order evolution equations with memory. By constructing a suitable measure of noncompactness on the space of solutions, we prove the existence ...
