On the typical rank of real binary forms
We determine the rank of a general real binary form of degree d = 4 and d = 5. In the case d = 5, the possible values of the rank of such general forms are 3, 4, 5. The existence of three typical ranks was unexpected. We prove that a real binary form of degree d with d real roots has rank d.
متن کاملCurvilinear Schemes and Maximum Rank of Forms
We define the curvilinear rank of a degree d form P in n+1 variables as the minimum length of a curvilinear scheme, contained in the d-th Veronese embedding of Pn, whose span contains the projective class of P . Then, we give a bound for rank of any homogenous polynomial, in dependance on its curvilinear rank.
متن کاملFine Gradings of Low-Rank Complex Lie Algebras and of Their Real Forms⋆
In this review paper, we treat the topic of fine gradings of Lie algebras. This concept is important not only for investigating the structural properties of the algebras, but, on top of that, the fine gradings are often used as the starting point for studying graded contractions or deformations of the algebras. One basic question tackled in the work is the relation between the terms ‘grading’ a...
متن کاملDegrees of Projections of Rank Loci
We provide formulas for the degrees of the projections of the locus of square matrices with given rank from linear spaces spanned by a choice of matrix entries. The motivation for these computations stem from applications to ‘matrix rigidity’; we also view them as an excellent source of examples to test methods in intersection theory, particularly computations of Segre classes. Our results are ...
متن کاملJordan Forms of Real and Complex Matrices under Rank One Perturbations
New perturbation results for the behavior of eigenvalues and Jordan forms of real and complex matrices under generic rank one perturbations are discussed. Several results that are available in the complex case are proved as well for the real case and the assumptions on the genericity are weakened. Rank one perturbations that lead to maximal algebraic multiplicities of the “new” eigenvalues are ...
