On 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 کاملWhitney 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 کاملOn 5-dimensional 2-step homogeneous randers nilmanifolds of Douglas type
In this paper we first obtain the non-Riemannian Randers metrics of Douglas type on two-step homogeneous nilmanifolds of dimension five. Then we explicitly give the flag curvature formulae and the $S$-curvature formulae for the Randers metrics of Douglas type on these spaces. Moreover, we prove that the only simply connected five-dimensional two-step homogeneous Randers nilmanifolds of D...
متن کاملDeformation of 2-Step Nilmanifolds with Abelian Complex Structures
We develop deformation theory for abelian invariant complex structures on a nilmanifold, and prove that in this case the invariance property is preserved by the Kuranishi process. A purely algebraic condition characterizes the deformations leading again to abelian structures, and we prove that such deformations are unobstructed. Various examples illustrate the resulting theory, and the behavior...
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.
