The invariants of the third symmetric power representation of SL_2(F_p) [PDF]
For a prime p>3, we compute a finite generating set for the SL_2(F_p)-invariants of the third symmetric power representation. The proof relies on the construction of an infinite SAGBI basis and uses the Hilbert series calculation of Hughes and ...

On the coinvariants of modular representations of cyclic groups of prime order [PDF]
We consider the ring of coinvariants for modular representations of cyclic groups of prime order. For all cases for which explicit generators for the ring of invariants are known, we give a reduced Gröbner basis for the Hilbert ideal and the ...

Multiplicities of some graded сocharacters of the matrix superalgebra M(2,2)(F) [PDF]
Let $F$ be an arbitrary field of characteristic zero, and let $M^{(m,k)}(F)$ be a matrix superalgebra over $F$. It is known from the theory of algebras with polynomial identities that the superalgebra $M^{(m,k)}(F)$ has a finite basis of $Z_2$-graded ...

Zassenhaus conjecture for central extensions of S5 [PDF]
We confirm a conjecture of Zassenhaus about rational conjugacy of torsion units in integral group rings for a covering group of the symmetric group S5 and for the general linear group GLð2; 5Þ. The first result, together with others from the literature,

On irreducible projective representations of finite groups [PDF]
The paper is a survey type article inwhich we present some results on irreducible projective representations offinite groups. Section 2 includes Curtis and Reiner's theorem inwhich is proved that a finite group has at most a finite number ofinequivalent ...

Symmetrical Powers of Representations of Finite Groups
The main result is that if \(V\) is a finite dimensional faithful module for a finite group \(G\) over a field \(K\) and \(c\) is the number of elements of \(G\) which have scalar action on \(V\) then, for large values of \(n\), the sum of \(c\) consecutive symmetric powers \(S_n(V) \oplus S_{n + 1} (V) \oplus \cdots \oplus S_{n + c - 1} (V)\) is close

Derived Picard groups of symmetric representation-finite algebras of type $D$
We explicitly describe the derived Picard groups of symmetric representation-finite algebras of type $D$. In particular, we prove that these groups are generated by spherical twists along collections of $0$-spherical objects, the shift and autoequivalences which come from outer automorphisms of a particular representative of the derived equivalence ...

The Noether numbers for cyclic groups of prime order [PDF]
The Noether number of a representation is the largest degree of an element in a minimal homogeneous generating set for the corresponding ring of invariants.

On the distance eigenvalues of Cayley graphs
In this paper, graphs are undirected and loop-free and groups are finite. By Cn, Kn and Km,n we mean the cycle graph with n vertices, the complete graph with n vertices and the complete bipartite graph with parts size m and n, respectively.

Symmetric Presentations of Coxeter Groups
We apply the techniques of symmetric generation to establish the standard presentations of the finite simply laced irreducible finite Coxeter groups, that is, the Coxeter groups of types An, Dn and En, and show that these are naturally arrived at purely ...
