Gonii: Universal Quaternary Quadratic Forms
We continue our study of quadratic forms using Geometry of Numbers methods by considering universal quaternary positive definite integral forms of square discriminant. We give a small multiple theorem for such forms and use it to prove universality for all nine universal diagonal forms. The most interesting case is x2 + 2y2 + 5z2 + 10w2, which required computer calculations.
متن کامل-Valued Quadratic Forms and Quaternary Sequence Families
In this paper, -valued quadratic forms defined on a vector space over are studied. A classification of such forms is established, distinguishing -valued quadratic forms only by their rank and whether the associated bilinear form is alternating. This result is used to compute the distribution of certain exponential sums, which occur frequently in the analysis of quaternary codes and quaternary s...
متن کاملApplications of quadratic D-forms to generalized quadratic forms
In this paper, we study generalized quadratic forms over a division algebra with involution of the first kind in characteristic two. For this, we associate to every generalized quadratic from a quadratic form on its underlying vector space. It is shown that this form determines the isotropy behavior and the isometry class of generalized quadratic forms.
متن کاملZ4-valued quadratic forms and quaternary sequence families
Z4-valued quadratic forms defined on a vector space over GF(2) are studied. A classification of such forms is established, distinguishing Z4-valued quadratic forms only by their rank and whether the associated bilinear form is alternating or not. This result is used to compute the distribution of certain exponential sums, which occur frequently in the analysis of quaternary codes and quaternary...
متن کاملA General Correspondence between Dirichlet Forms and Right Processes
The theory of Dirichlet forms as originated by Beurling-Deny and developed particularly by Fukushima and Silverstein, see e.g. [Fu3, Si], is a natural functional analytic extension of classical (and axiomatic) potential theory. Although some parts of it have abstract measure theoretic versions, see e.g. [BoH] and [ABrR], the basic general construction of a Hunt process properly associated with ...
