    • Degree of reductivity of a modular representation 

      Kohls, M.; Sezer, M. (World Scientific Publishing, 2017)
      For a finite-dimensional representation V of a group G over a field F, the degree of reductivity δ(G,V) is the smallest degree d such that every nonzero fixed point υ ∈ VG/{0} can be separated from zero by a homogeneous ...

    • Hilbert ideals of vector invariants of s2 and S3 

      Sezer, M.; Ünlü, Ö. (Heldermann Verlag, 2012)
      The Hilbert ideal is the ideal generated by positive degree invariants of a finite group. We consider the vector invariants of the natural action of S n . For S 2 we compute the reduced and universal Gröbner bases for the ...

    • Separating invariants for the klein four group and cyclic groups 

      Kohls, M.; Sezer, M. (World Scientific Publishing, 2013-06-11)
      We consider indecomposable representations of the Klein four group over a field of characteristic 2 and of a cyclic group of order pm with p, m coprime over a field of characteristic p. For each representation, we explicitly ...
