For a local maximal function defined on a certain family of cubes lying “well inside” of Ω , a proper open subset of Rn, we characterize the couple of weights (u, v) for which it is bounded from Lp(v) on Lq(u).

We aim to prove inequalities of the form | δk - λ (x, t) ∇k u (x, t) | ≤ C MR+- MD#, λ, k u (x, t) for solutions of frac(∂ u, ∂ t) = Δ u on a domain Ω = D × R+, where δ (x, t) is the parabolic distance of (x, t) to parabolic ...

It was aimed at, with the present work, to investigate the possible association between the buccal plane lichen and the chronic hepatitis for the virus C. With the approval of the Committee of Ethics of UFMG, and after ...

Some local versions of the Bishop–Phelps–Bollobás property for operators have been recently presented in Dantas et al. (J Math Anal Appl 468(1):304–323, 2018). In the present article, we continue studying these properties ...
