Incidence Properties of Cosets in Loops
We study incidence properties among cosets of finite loops, with emphasis on well-structured varieties such as antiautomorphic loops and Bol loops. While cosets in groups are either disjoint or identical, we find that the incidence structure in general loops can be much richer. Every symmetric design, for example, can be realized as a canonical collection of cosets of a finite loop. We show tha...
متن کاملOn cryptographic properties of the cosets of R(1, m)
We introduce a new approach for the study of weight distributions of cosets of the Reed–Muller code of order 1. Our approach is based on the method introduced by Kasami in [1], using Pless identities. By interpreting some equations, we obtain a necessary condition for a coset to have a “high” minimum weight. Most notably, we are able to distinguish such cosets which have three weights only. We ...

15 صفحه اولProperties of Chiral Wilson Loops
We study a class of Wilson Loops in N = 4,D = 4 Yang-Mills theory belonging to the chiral ring of a N = 2, d = 1 subalgebra. We show that the expectation value of these loops is independent of their shape. Using properties of the chiral ring, we also show that the expectation value is identically 1. We find the same result for chiral loops in maximally supersymmetric Yang-Mills theory in three,...
متن کاملGauging Cosets
We show how to gauge the set of raising and lowering generators of an arbitrary Lie algebra. We consider SU(N) as an example. The nilpotency of the BRST charge requires constraints on the ghosts associated to the raising and lowering generators. To remove these constraints we add further ghosts and we need a second BRST charge to obtain nontrivial cohomology. The second BRST operator yields a g...
