چکیده

For a prime number p, we construct a generating set for the ring of invariants for the p+1 dimensional indecomposable modular representation of a cyclic group of order p. We then use the constructed invariants to describe the decomposition of the symmetric algebra as a module over the group ring, confirming the Periodicity Conjecture of Ian Hughes and Gregor Kemper for this case.

DECOMPOSING SYMMETRIC POWERS OF MODULAR REPRESENTATIONS OF ELEMENTARY ABELIAN p-GROUPS

Let G be a elementary abelian p-group of order q = p. Let V be a faithful indecomposable modular representation of G with dimension 2. We consider representations of the form S(S(V )). In particular we prove that S(S(V )) is projective whenever d+m ≥ q, and either d < p and m < q or m < p and d < q. More generally we show that if d+m ≥ q and d < q, m < q, then each summand of S(S(V )) is induce...

On Symmetric Power L-invariants of Iwahori Level Hilbert Modular Forms

We compute the arithmetic L-invariants (of Greenberg–Benois) of twists of symmetric powers of p-adic Galois representations attached to Iwahori level Hilbert modular forms (under some technical conditions). Our method uses the automorphy of symmetric powers and the study of analytic Galois representations on p-adic families of automorphic forms over symplectic and unitary groups. Combining thes...

Symmetric Powers of Modular Representations for Groups with a Sylow Subgroup of Prime Order

Let V be a representation of a finite group G over a field of characteristic p. If p does not divide the group order, then Molien’s formula gives the Hilbert series of the invariant ring. In this paper we find a replacement of Molien’s formula which works in the case that |G| is divisible by p but not by p. We also obtain formulas which give generating functions encoding the decompositions of a...

Branching of Modular Representations of the Alternating Groups

Based on Kleshchev's branching theorems for the p-modular irreducible representations of the symmetric group and on the recent proof of the Mullineux Conjecture, we investigate in this article the corresponding branching problem for the p-modular irreducible representations of the alternating group A n. We obtain information on the socle of the restrictions of such A n-representations to A n?1 ...

Maximal Ideals in Modular Group Algebras of the Finitary Symmetric and Alternating Groups

The main result of the paper is a description of the maximal ideals in the modular group algebras of the finitary symmetric and alternating groups (provided the characteristic p of the ground field is greater than 2). For the symmetric group there are exactly p − 1 such ideals and for the alternating group there are (p − 1)/2 of them. The description is obtained in terms of the annihilators of ...
