Modules for Elementary Abelian p-groups
Let E ∼= (Z/p)r (r ≥ 2) be an elementary abelian p-group and let k be an algebraically closed field of characteristic p. A finite dimensional kE-module M is said to have constant Jordan type if the restriction of M to every cyclic shifted subgroup of kE has the same Jordan canonical form. I shall begin by discussing theorems and conjectures which restrict the possible Jordan canonical form. The...
متن کاملThe Dirac Operator over Abelian Finite Groups
In this paper we show how to construct a Dirac operator on a lattice in complete analogy with the continuum. In fact we consider a more general problem, that is, the Dirac operator over an abelian finite group (for which a lattice is a particular example). Our results appear to be in direct connexion with the so called fermion doubling problem. In order to find this Dirac operator we need to in...
متن کاملPseudo-Free Families of Finite Computational Elementary Abelian p-Groups
We initiate the study of (weakly) pseudo-free families of computational elementary abelian pgroups, where p is an arbitrary fixed prime. We restrict ourselves to families of computational elementary abelian p-groups Gd such that for every index d, each element of Gd is represented by a single bit string of length polynomial in the length of d. First, we prove that pseudo-freeness and weak pseud...
متن کاملCritical sets in the elementary abelian 2- and 3- groups
In 1998, Khodkar showed that the minimal critical set in the Latin square corresponding to the elementary abelian 2-group of order 16 is of size at most 124. Since the paper was published, improved methods for solving integer programming problems have been developed. Here we give an example of a critical set of size 121 in this Latin square, found through such methods. We also give a new upper ...
متن کاملElementary Abelian Hopf Galois Structures and Polynomial Formal Groups
We find a relationship between regular embeddings of G, an elementary abelian p-group of order p, into unipotent upper triangular matrices with entries in Fp and commutative dimension n degree 2 polynomial formal groups with nilpotent upper triangular structure matrices. We classify the latter when n = 3 up to linear isomorphism, and use that classification to determine the number of Hopf Galoi...
