Vector representable matroids of given rank with given automorphism group
A simple way of as,;ociating a matroid of prescribed rank with a graph is shown. The matroids so corhstrueted are re.presentable over any sufficiently large field. Their ase is demonstrated by the fallowing result: Given an integer k >~ 3 and a hmction G associating a group with each subsel of a set S, the'e is a matroid M(E), representable ever any sufl]ciendy large field, such that E ~S, and ...
متن کاملOn the construction of dense lattices with a given automorphism group
We consider the problem of constructing dense lattices of Rn with a given non trivial automorphism group. We exhibit a family of such lattices of density at least cn2−n, which matches, up to a multiplicative constant, the best known density of a lattice packing. For an infinite sequence of dimensions n, we exhibit a finite set of lattices that come with an automorphism group of size n, and a co...
متن کاملOn the directed triple systems with a given automorphism
A directed triple system of order v, denoted DTS(v), is said to be f-bicyclic if it admits an automorphism consisting of f fixed points and two disjoint cycles. In this paper, we give necessary and sufficient conditions for the existence of f-bicyclic
متن کاملSubdirectly Reducible Groups and Edge-minimal Graphs with given Automorphism Group
A group is subdirectly reducible if it has two non-trivial normal subgroups with trivial intersection. Such groups may be an easy case in certain inductive arguments. We prove that every solvable finite group can be generated by at most one subdirectly reducible subgroup together with two subgroups of prime-power order and one element. We also prove that every group of prime-power order can be ...
متن کاملThe Automorphism Group of a Lie Group
Introduction. The group A (G) of all continuous and open automorphisms of a locally compact topological group G may be regarded as a topological group, the topology being defined in the usual fashion from the compact and the open subsets of G (see §1). In general, this topological structure of A(G) is somewhat pathological. For instance, if G is the discretely topologized additive group of an i...
