Whitney Forms of Higher Degree
Low order Whitney elements are widely used for electromagnetic field problems. Higher order approximations are receiving increasing interest but their definition remains unduly complex. In this paper we propose a new simple construction for Whitney p-elements of polynomial degree higher than one that use only degrees of freedom associated to p-chains. We provide a basis for these elements on si...
متن کاملWitt rings of quadratically presentable fields
This paper introduces an approach to the axiomatic theory of quadratic forms based on {tmem{presentable}} partially ordered sets, that is partially ordered sets subject to additional conditions which amount to a strong form of local presentability. It turns out that the classical notion of the Witt ring of symmetric bilinear forms over a field makes sense in the context of {tmem{quadratically p...
متن کاملWitt Rings and Matroids
The study of Witt rings of formally real fields in the algebraic theory of quadratic forms has led to a particularly good understanding of the finitely generated torsion free Witt rings. In this paper, we work primarily with a somewhat more general class of rings which can be completely characterized by (binary) matroids. The different types of standard constructions and invariants coming from ...
متن کاملOn the centers of higher degree forms
Let Θ be a symmetric d-linear form on a vector space V of dimension n over a field K. Its center, Cent(V,Θ), is the analog of the space of symmetric matrices for a bilinear form. If d > 2, the center is a commutative subalgebra of EndK(V ). It was conjectured in [4] that the center has dimension at most n and a proof was given for n ≤ 5. We construct counter examples to this conjecture. We give...
متن کاملU-invariants for Forms of Higher Degree
Both a general and a diagonal u-invariant for forms of higher degree are defined, generalizing the u-invariant of quadratic forms. Both old and new results on these invariants are collected.
