Representations of SL over finite local rings of length two
نویسندگان
چکیده
Let Fq be a finite field of characteristic p and let W2(Fq) the ring Witt vectors length two over Fq. We prove that for any integer n such divides n, groups SLn(Fq[t]/t2) SLn(W2(Fq)) have same number irreducible representations dimension d, each d.

Representations of Reductive Groups over Finite Rings
In this paper we construct a family of irreducible representations of a Chevalley group over a finite ring R of truncated power series over a field Fq . This is done by a cohomological method extending that of Deligne and the author in the case R = Fq .
متن کاملKernel representations for behaviors over finite rings
In behavioral theory, a central role is played by the set B of trajectories that belong to a dynamical system Σ, see the textbook [11]. In fact, the dynamical system is defined as a triple Σ = (T,W,B), where T is the time axis, W is the signal alphabet, and where B, the behavior of the system, is a subset of W. In this paper we consider dynamical systems Σ = (Z+,R ,B), where R is the ring Zpr ....
متن کاملRepresentations of GL(2) and SL(2) over finite fields
Irreducible complex representations of GL(2) and SL(2) over a finite field can be classified by methods useful for p-adic reductive groups and real Lie groups. (See Piatetski-Shapiro’s inspiring A.M.S. Memoir on this subject.) That is, we first see that most principal series representations are irreducible. We determine the irreducible constituents of the irregular principal series. We prove th...
متن کاملUnramified Representations of Reductive Groups over Finite Rings
Lusztig has given a construction of certain representations of reductive groups over finite local principal ideal rings of characteristic p, extending the construction of Deligne and Lusztig of representations of reductive groups over finite fields. We generalize Lusztig’s results to reductive groups over arbitrary finite local rings. This generalization uses the Greenberg functor and the theor...
متن کاملResidually Reducible Representations of Algebras over Local Artinian Rings
In this paper we generalize a result of Urban on the structure of residually reducible representations on local Artinian rings from the case that the semi-simplification of the residual representation splits into 2 absolutely irreducible representations to the case where it splits into m ≥ 2 absolutely irreducible representations.
