Estimates for the Multiplicative Square Function of Solutions to Nondivergence Elliptic Equations

open access: yesAbstract and Applied Analysis, 2007
We prove distributional inequalities that imply the comparability of the Lp norms of the multiplicative square function of u and the nontangential maximal function of logu, where u is a positive solution of a nondivergence elliptic equation. We also give

Moduli of Continuity and Absolute Continuity: Any Relation?

open access: yesResults in Mathematics
We construct a monotone, continuous, but not absolutely continuous function whose minimal modulus of continuity is absolutely continuous. In particular, we establish that there is no equivalence between the absolute continuity of a function and the absolute continuity of its modulus of continuity, in contrast with a well-known property of Lipschitz ...
