The Smallest Faithful Representation of a Certain Extension of Sl2
نویسنده
چکیده
LetG be the six dimensional linear algebraic k-group SL2(W2), where W2 is the ring of Witt vectors of length two over the algebraically closed field k of characteristic p > 0. Then the minimal dimension of a faithful rational krepresentation of G is p + 3.

QUASI-PERMUTATION REPRESENTATIONS OF SUZtTKI GROUP
By a quasi-permutation matrix we mean a square matrix over the complex field C with non-negative integral trace. Thus every permutation matrix over C is a quasipermutation matrix. For a given finite group G, let p(G) denote the minimal degree of a faithful permutation representation of G (or of a faithful representation of G by permutation matrices), let q(G) denote the minimal degree of a fai...

متن کاملTHE LEFT REGULAR REPRESENTATION OF A COMMUTATIVE SEPARATIVE SEMIGROUP
In this paper, a commutative semigroup will be written as a disjoint union of its cancellative subsemigroups. Based on this fact we will define the left regular representation of a commutative separative semigroup and show that this representation is faithful. Finally concrete examples of commutative separative semigroups, their decompositions and their left regular representations are given.
متن کاملSmall representations of SL2 in the finite Morley rank category
We study definable irreducible actions of SL2(K) on an abelian group of Morley rank ≤ 3rk(K) and prove they are rational representations of the group. In this article we consider representations of SL2 which are interpretable in finite Morley rank theories, meaning that inside a universe of finite Morley rank we shall study the following definable objects: a group G isomorphic to SL2, an abelia...
