A remark on weighted inequalities for general maximal operators
(American Mathematical Society, 1993-12)Let 1 < p < ∞, and let w, v be two non–negative functions. We give a sufficient condition on w, v for which the general ...

A zero of a proper mapping
(Casa Cărţii de Ştiinţă Cluj-Napoca, 2003)Sufficient conditions are given to assert that a differentiable proper Fredholm mapping between Banach spaces over K = R or K = C has a zero. The proof of the result is constructive and is based upon continuation methods.

A1 bounds for Calderón-Zygmund operators related to a problem of Muckenhoupt and Wheeden
(International Press, 2009)We obtain an Lp(w) bound for Calderón-Zygmund operators T when w ∈ A1. This bound is sharp both with respect to ∥w∥A1 and with respect to p. As a result, we get a new L1,∞(w) estimate for T related to a problem of Muckenhoupt and Wheeden.

About some families of nonexpansive mappings with respect to renorming
(Hindawi Publishing Corporation, 2016)We characterize the family of nonexpansive mappings which are invariant under renormings and we also compare the families of nonexpansive mappings under two equivalent norms.
