Binary Forms , Hypergeometric
In a previous paper, it was shown that if F is a binary form with complex coeecients having degree n 3 and discrimi-nant D F 6 = 0, and if A F is the area of the region jF(x; y)j 1 in the real aane plane, then jD F j 1=n(n?1)
متن کاملQuaternary binary trilinear forms
Dear friends, In 1997 or 1998 I began to write a paper [20], trying to extend the known description of binary forms of norm unity, in the real or complex cases, to the case of quaternions, but I never finished it. In 2002, I resumed my work but then I was unable to understand what I had done, so I made a fresh start with somewhat different assumptions. Now I have realized that this was a gross ...
متن کاملUniversal binary Hermitian forms
We will determine (up to equivalence) all of the integral positive definite Hermitian lattices in imaginary quadratic fields of class number 1 that represent all positive integers.
متن کاملBinary/ternary extreme learning machines
In this paper, a new hidden layer construction method for Extreme Learning Machines (ELMs) is investigated, aimed at generating a diverse set of weights. The paper proposes two new ELM variants: Binary ELM, with a weight initialization scheme based on f0;1g–weights; and Ternary ELM, with a weight initialization scheme based on f 1;0;1g–weights. The motivation behind this approach is that these ...
متن کاملNormal forms for binary relations
We consider the representable equational theory of binary relations, in a language expressing composition, converse, and lattice operations. By working directly with a presentation of relation expressions as graphs we are able to define a notion of reduction which is confluent and strongly normalizing and induces a notion of computable normal form for terms. This notion of reduction thus leads ...
