Variations on Browder ’ S Theorem
In this note we introduce and study the new spectral properties (Bb), (Bab) and (Baw) as continuation of [7, 8, 12] which are variants of the classical Browder’s theorem.
متن کاملVariations on the Tait-Kneser theorem
At every point, a smooth plane curve can be approximated, to second order, by a circle; this circle is called osculating. One may think of the osculating circle as passing through three infinitesimally close points of the curve. A vertex of the curve is a point at which the osculating circle hyper-osculates: it approximates the curve to third order. Equivalently, a vertex is a critical point of...
متن کاملVariations on the Dembowski-Wagner theorem
Let D be a symmetric design admitting a null polarity such that either all singular lines, or all nonsingular lines, have size (v − λ)/(k − λ); assume that this number is greater than λ in the case of singular lines. Then D is either a projective space or an orthogonal symmetric design. © 2003 Elsevier Ltd. All rights reserved. The Dembowski–Wagner Theorem [3] characterizes projective spaces as...
متن کاملVariations on the Projective Central Limit Theorem
This expository article states and proves four, concrete, projective, central limit theorems. The results are known or suspected to be true by experts who are familiar with the more general central limit theorem for convex bodies, and related theory. Here we consider only four types of high dimensional geometric objects: spheres, balls, cubes, and boundaries of cubes. Each is capable of transfo...
متن کاملVariations on Kuratowski's 14-Set Theorem
Apparently Question 1.2 will require us to solve 2 = 32 different problems... well, not really. Many of these are redundant, either because different choices of I allow us to perform the same operations, or because different choices of I raise algebraically isomorphic questions. (This is explained in Section 4.) Theorem 1.1 answers at least one case, and certainly many others are trivial. Final...
