Automorphism group of split Cartan modular curves
We determine the automorphism group of the split Cartan modular curves Xsplit(p) for all primes p.
متن کاملMumford Curves with Maximal Automorphism Group
It is known that a Mumford curve of genus g / ∈ {5, 6, 7, 8} over a non-archimedean valued field of characteristic p > 0 has at most 2 √ g( √ g+1) automorphisms. In this note, the unique family of curves which attains this bound, and their automorphism group are determined.
متن کاملThe Locus of Curves with Prescribed Automorphism Group
Let G be a finite group, and g ≥ 2. We study the locus of genus g curves that admit a G-action of given type, and inclusions between such loci. We use this to study the locus of genus g curves with prescribed automorphism group G. We completely classify these loci for g = 3 (including equations for the corresponding curves), and for g ≤ 10 we classify those loci corresponding to " large " G.
متن کاملAUTOMORPHISM GROUP OF GROUPS OF ORDER pqr
H"{o}lder in 1893 characterized all groups of order $pqr$ where $p>q>r$ are prime numbers. In this paper, by using new presentations of these groups, we compute their full automorphism group.
متن کاملTHE AUTOMORPHISM GROUP OF FINITE GRAPHS
Let G = (V,E) be a simple graph with exactly n vertices and m edges. The aim of this paper is a new method for investigating nontriviality of the automorphism group of graphs. To do this, we prove that if |E| >=[(n - 1)2/2] then |Aut(G)|>1 and |Aut(G)| is even number.
