Computations and Equations for Segre-grassmann Hypersurfaces
In 2013, Abo and Wan studied Waring’s problem for systems of skew-symmetric forms and identified several defective systems. The cases of particular interest occur when a certain secant variety of a Segre-Grassmann variety is expected to fill the natural ambient space, but is actually a hypersurface. In these cases, one aims to obtain both a defining polynomial for these hypersurfaces along with...
متن کاملToolbox for Grassmann Manifold Computations
This a description and user guide for an object oriented toolbox written in matlab for computations defined on Grassmann manifolds and products of Grassmann manifolds. It implements basic operations as geodesic movement and parallel transport of tangent vectors. 1 Content of toolbox There are two classes: • @grass — Contains functions, methods and operations for objects on one Grssmannian. • @p...
متن کاملGrassmann and Segre varieties over GF(2): some graph theory links
Some recent results (and a conjecture) concerning the polynomial degree of the Grassmannian G1;n;2 of the lines of PG(n; 2) are shown to be equivalent to results (and a conjecture) concerning certain kinds of subgraphs of any (simple) graph = (V; E) which is of order jVj = n+ 1: It turns out that those graphs of size jEj = n = jVj 1 are of particular signi cance. Somewhat similarly, results con...
متن کاملglobal results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Generalizations of Strassen’s equations for secant varieties of Segre varieties
We define many new examples of modules of equations for secant varieties of Segre varieties that generalize Strassen’s commutation equations [7]. Our modules of equations are obtained by constructing subspaces of matrices from tensors that satisfy various commutation properties.
