Detailed Structure for Freiman ’ s 3 k − 3 Theorem
Let A be a set of k integers. We study Freiman’s inverse problem with small doublings and continue the work of G. A. Freiman, I. Bardaji and D. J. Grynkiewicz by characterizing the detailed structure of A in Theorem 2.2 below when the sumset A + A contains exactly 3k−3 integers. Besides some familiar structures, such a set A can have a configuration composed of “additively minimal triangles.”
متن کاملA Structure Theorem for Stationary Perfect Fluids
It is proven that, under mild physical assumptions, an isolated stationary relativistic perfect fluid consists of a finite number of cells fibred by invariant annuli or invariant tori. For axially symmetric circular flows it is shown that the fluid consists of cells fibred by rigidly rotating annuli or tori.
متن کاملA REMEZ - TYPE INEQUALITY 3 Theorem 1
The principal result of this paper is a Remez-type inequality for M untz polynomials: p(x) := n X i=0 a i x i ; or equivalently for Dirichlet sums: P(t) := n X i=0 a i e ? i t ; where (i) 1 i=0 is a sequence of distinct real numbers. The most useful form of this inequality states that for every sequence (i) 1 i=0 satisfying 1 X i=0 i 6 =0 1 j i j < 1 there is a constant c depending only on (i) ...
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولStructure Theory for a Class of Grade Four Gorenstein Ideals
An ideal / in a commutative noetherian ring R is a Gorenstein ideal of grade g if pdR(R/I) = grade I = g and the canonical module HxtsR(R/I, R) is cyclic. Serre showed that if g = 2 then / is a complete intersection, and Buchsbaum and Eisenbud proved a structure theorem for the case g = 3. We present generic resolutions for a class of Gorenstein ideals of grade 4, and we illustrate the structur...
