This paper studies the approximation of the Hilbert transform f = H f of continuous functions f with continuous conjugate f… (More)

We investigate the rate of convergence of linear sampling numbers of the embedding Hα,β (Td ) ↩→ Hγ (Td ). Here α governs the… (More)

The problem of finding the zeros of the sum of two maximally monotone operators is of fundamental importance in optimization and… (More)

We present results on interpolation and L1-approximation of periodic functions by trigonometric polynomials and trigonometric… (More)

It is well known that for any bounded Lipschitz graph domain Ω ⊂ Rd , r ≥ 1 and 1 ≤ p ≤ ∞ there exist constants C1 (d, r) ,C2… (More)

In collecting material for an autobiographical statement, I realized that I had been privileged to experience and participate in… (More)
