    • Constructing modular separating invariants 

      Sezer, M. (2009)
      We consider a finite dimensional modular representation V of a cyclic group of prime order p. We show that two points in V that are in different orbits can be separated by a homogeneous invariant polynomial that has degree ...
    • 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 ...
    • Explicit separating invariants for cyclic p-groups 

      Sezer, M. (Elsevier, 2011-02)
      We consider a finite-dimensional indecomposable modular representation of a cyclic p-group and we give a recursive description of an associated separating set: We show that a separating set for a representation can be ...
    • Lexsegment and Gotzmann ideals associated with the diagonal action of Z/p 

      Sezer, M. (Springer Wien, 2011)
      We consider a diagonal action of a cyclic group of prime order on a polynomial ring F[x1,...,xn]. We give a description of the actions for which the corresponding Hilbert ideal is Gotzmann when n = 2. Nevertheless, we show ...
    • 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 ...
