REGULARITY OF THE FRACTIONAL MAXIMAL FUNCTION

Bulletin of the London Mathematical Society, 2003
The purpose of this work is to show that the fractional maximal operator has somewhat unexpected regularity properties. Our main result shows that the fractional maximal operator maps \(L^p\)-spaces boundedly into certain first-order Sobolev spaces. We also prove that the fractional maximal operator preserves first-order Sobolev spaces.

Maximal ? -regularity

2015
In this paper, we prove maximal regularity estimates in “square function spaces” which are commonly used in harmonic analysis, spectral theory, and stochastic analysis. In particular, they lead to a new class of maximal regularity results for both deterministic and stochastic equations in L p -spaces with ...

Regular, Commutative, Maximal Semigroups of Quotients

Canadian Mathematical Bulletin, 1975
A well-known theorem which goes back to R. E. Johnson [4], asserts that if R is a ring then Q(R), its maximal ring of quotients is regular (in the sense of v. Neumann) if and only if the singular ideal of R vanishes. In the theory of semigroups a natural question is therefore the following: Do there exist properties which characterize those semigroups ...

Perturbation theorems for maximal \(L_p\)-regularity

2001
The authors consider perturbation theorems for \(R\)-sectorial operators. Let \(A\) be an \(R\)-sectorial operator in a Banach space \(X\). Let \(B\) be a perturbation for \(A\) which is relatively small with respect to \(A\). Then \(A+B\) is also \(R\)-sectorial. This result seems to be a generalization of the Kato-Rellich Theorem and the KLMN-Theorem.

Maximally regular planar parallel robots

2010
Maximally regular planar parallel robots are actuated by one rotating and two linear actuators and can have various degrees of overconstraint. In these solutions, the three operational velocities are equal to their corresponding actuated joint velocities: \({\it v}_1=\dot{q}_1,{\it v}_2=\dot{q}_2\)and\(\omega_\delta=\dot{q}_3.\)The Jacobian matrix in ...
