Cyclic automorphisms beyond the canonical bound
Ahmad Kazemifard, Saeed Tafazolian
Let X be a smooth projective curve of genus g >= 2 over an algebraically closed field K, and suppose that Aut(X) contains a cyclic subgroup G of order N > 2g - 2. The cases N >= 2g…

On the generalized Ree curve
Ahmad Kazemifard, Saeed Tafazolian
Let p be an odd prime, let q_0 := p^s with s >= 1, and put q := p q_0^2. We study the smooth projective curve R_{p,s} with function field F_q(x,y,z), y^q - y = x^{q_0}(x^q - x), z^…
