Half-cycles and chaplets
For n odd, a half-cycle for Zn is a cycle [a1, a2, . . . , am] of distinct elements from Zn such that (a) m = (n − 1)/2, (b) the elements ai (i = 1, 2, . . . ,m) are all distinct, and (c) the differences ai+1 − ai (i = 1, 2, . . . ,m, with am+1 = a1) are all distinct and no two of them are the negatives of one another, modulo n. Similarly, a chaplet for Zn is now newly defined to be a cycle [a1...
متن کاملEquivariant Vector Bundles on Drinfeld ’ S Upper Half Space Sascha
Let X ⊂ PdK be Drinfeld’s upper half space over a finite extension K of Qp. We construct for every GLd+1-equivariant vector bundle F on PdK , a GLd+1(K)equivariant filtration by closed subspaces on the K-Fréchet H(X ,F). This gives rise by duality to a filtration by locally analytic GLd+1(K)-representations on the strong dual H(X ,F). The graded pieces of this filtration are locally analytic in...
متن کاملOn light cycles in plane triangulations
A subgraph of a plane graph is light if each of its vertices has a small degree in the entire graph. Consider the class ~¢-(5) of plane triangulations of minimum degree 5. It is known that each G C,Y-(5) contains a light triangle. From a recent result of Jendrol' and Madaras the existence of light cycles C4 and C5 in each G C.~(5) follows. We prove here that each G E.Y-(5) contains also light c...
متن کاملHamilton cycles in plane triangulations
We extend Whitney’s Theorem that every plane triangulation without separating triangles is hamiltonian by allowing some separating triangles. More precisely we define a decomposition of a plane triangulation G into 4-connected ‘pieces’ and show that if each piece shares a triangle with at most three other pieces then G is hamiltonian. We provide an example to show that our hypothesis that ‘each...
متن کاملA special subspace of weighted spaces of holomorphic functions on the upper half plane
In this paper, we intend to define and study concepts of weight and weighted spaces of holomorphic (analytic) functions on the upper half plane. We study two special classes of these spaces of holomorphic functions on the upper half plane. Firstly, we prove these spaces of holomorphic functions on the upper half plane endowed with weighted norm supremum are Banach spaces. Then, we investigate t...
