For any convex polyhedron W in ℝ m , p ∈ (1,∞), and N > 1, there are constants γ 1 (W, p, m) and γ 2 (W, p,m) such that Similar results hold for more general regions. These results are various special cases of the inequalities where φ(N) = N p(m-1)/2 when p ∈ (1,2m/m+1), φ(N) = N p(m―1)/2 log N when p = 2m/m+1, and φ(N) = N m(p-1) when p > 2m/m+1 where B is a bounded subset of ℝ m with non-empty interior.

We provide L p →L q estimates for a class of Fourier multipliers supported in convex cones of { R } n+1. In particular, we consider cones whose boundary has n−1 nonvanishing principal curvatures and cones which are the convex envelope of N linearly independent half lines passing through the origin of { R } n+1. In some case our estimates are best possible.

We discuss existence and stability of Riesz bases of exponential type of L^2(T) for special domains T called trapezoids. We construct exponential bases on L^2(T) when T is a finite union of rectangles with the same height. We also generalize our main theorems in dimension d\ge 3.

Let m be a bounded and monotonic function on R with λ=infm and Λ=supm. We study the best constant in the inequality ‖Tmf‖p≤c‖f‖p for 1<p<∞, where Tm is the Fourier multiplier associated to m. Our result is completely explicit when Λ=−λ and when Λ·λ=0. We also discuss the case of m with bounded variation.

We show that the discrete Hilbert transform and the discrete Kak-Hilbert transform are infinitesimal generator of one-parameter groups of operators

In this paper we prove the sharp inequality |Pn(s)(x)| = Pn(s)(1) (|x|n + {n-1}/{2 s+1} (1 - |x|n)), where Pn(s)(x) is the classical ultraspherical polynomial of degree n and order s = n frac{1 + v 5}{4}. This inequality can be refined in [0, zns] and [zns, 1], where zns denotes the largest zero of Pn(s) (x).

In this paper we prove a unique continuation theorem for elliptic operators of the formP(D)+V(x), whereP(D) has orderm≥2 and simple complex characteristics, andV(x)∈Ln/m(Rn). To prove our main theorem we use a restriction theorem for the Fourier transform to manifolds of codimension 2.
