Let and let be a (generalized) Steinberg representation of . It is well known that the space of Iwahori fixed vectors in is one dimensional. The I…
Eigenspaces of Newforms with Nontrivial Character
Markos Karameris
Let denote the space of holomorphic cuspforms with Dirichlet character and modular subgroup . We will characterize the space of newforms $S_{k}^{new}(…
A computational proof of the existence of the Dual Isogeny
M. Karameris
For an elliptic curve over a perfect field , we present a proof of the existence of the dual isogeny using computational methods linked to Vélu's formulae instead of…
Distribution of the Sequence [m]P in Elliptic Curves
Markos Karameris
Major controversy surrounds the use of Elliptic Curves in finite fields as Random Number Generators. There is little information however concerning the "randomness" of different pr…
