On a Problem of G . G . Lorentz

Let C(B) denote the space of real-valued continuous functions on B. At the conference Harmonic Analysis and Approximations held at Nor Amberd in Armenia in September, 1998, the following general problem was posed by Professor George G. Lorentz. Find conditions on finite dimensional subspaces U and V so that U/V is a unicity set in the problem of best uniform approximation to elements of C(B). I...

Updates on Some Letters of George G. Lorentz to Me

I started my research in approximation theory in a time when George Lorentz was one of the central figures, an undisputed world expert, of the subject. It meant a lot to me that he paid a special attention to my work on polynomial inequalities, Markov and Bernstein type inequalities in particular. A few years later I had a feeling he viewed me as one of the leading experts of Müntz polynomials ...

Isoclinic Classification of Some Pairs $(G,G\')$ of $p$-Groups

‎‎The equivalence relation isoclinism partitions the class of all pairs of groups‎ ‎into families‎. ‎In this paper‎, ‎a complete classification of the set of all pairs $(G,G')$ is established‏‎,‎ whenever‎ $G$ is a $p$-group of order at most $p^5‎‏$‎ and ‎$p$ is a prime number greater than 3. Moreover‎, ‎the classification of pairs $(H,H')$ for extra special $p$-groups $H$ is also given.

. D G ] 8 M ay 2 00 3 SOME REMARKS ON G 2 - STRUCTURES

This article consists of some loosely related remarks about the geometry of G2-structures on 7-manifolds and is based on unpublished joint work with two other people: F. Reese Harvey and Steven Altschuler. After some preliminary background information about the group G2 and its representation theory, a set of techniques is introduced for calculating the differential invariants of G2-structures ...

Partial Generalizations of Some Conjectures in Locally Symmetric Lorentz Spaces

In this paper, first we give a notion for linear Weingarten spacelike hypersurfaces with P + aH = b in a locally symmetric Lorentz space Ln+1 1 . Furthermore, we study complete or compact linear Weingarten spacelike hypersurfaces in locally symmetric Lorentz spaces Ln+1 1 satisfying some curvature conditions. By modifying Cheng-Yau’s operator given in [7], we introduce a modified operator L and...
