The monodromy group of a truncated simplex
In this paper we investigate the monodromy groups of the truncated simplices of all possible ranks and investigate related structures. In particular, we demonstrate that the monodromy group of a truncated simplex is the direct product of symmetric groups.
متن کاملRigid local systems and relative motives with Galois group G 2
We construct a relative mixed motive whose `-adic realizations give rise to Galois representations of the absolute Galois group of Q whose images are isomorphic to the exceptional groups of Lie-type G2(Z`), if ` is a prime ≥ 5. The method of construction relies on Katz’ motivic description of rigid local systems with quasi-unipotent local monodromy.

The 2-Modular Characters of Conway's Third Group Co3
We determine the 2-modular character table of the third sporadic simple group of Conway, up to two ambiguities. In each of these cases we give the smallest possibility for the character, which is also very likely to be the correct answer.
متن کاملDuality on Hypermaps with Symmetric or Alternating Monodromy Group
Duality is the operation that interchanges hypervertices and hyperfaces on oriented hypermaps. The duality index measures how far a hypermap is from being self-dual. We say that an oriented regular hypermap has duality-type {l, n} if l is the valency of its vertices and n is the valency of its faces. Here, we study some properties of this duality index in oriented regular hypermaps and we prove...
