Uniform Algebras on Curves
The proofs use the notion of analytic structure in a maximal ideal space. J. Wermer first obtained results along these lines and further contributions were made by E. Bishop and H. Royden and then by G. Stolzenberg [5] who proved STOLZENBERG'S THEOREM. Let XQC be a polynomially convex set. Let KQC be a finite union of Q-curves. Then (XKJK)*—X\JK is a {possibly empty) pure 1-dimensional analytic...
متن کاملParallel Guaranteed Quality Delaunay Uniform Mesh Refinement
We present a theoretical framework for developing parallel guaranteed quality Delaunay mesh generation software, that allows us to use commercial off-the-shelf sequential Delaunay meshers for two-dimensional geometries. In this paper, we describe our approach for constructing uniform meshes, in other words, the meshes in which all elements have approximately the same size. Our uniform distribut...
متن کاملGRB afterglow light curves from uniform and non-uniform jets
It is widely believed that gamma-ray bursts are produced by a jet-like outflows directed towards the observer, and the jet opening angle(θj) is often inferred from the time at which there is a break in the afterglow light curves. Here we calculate the GRB afterglow light curves from a relativistic jet as seen by observers at a wide range of viewing angles (θv) from the jet axis, and the jet is ...
متن کاملA Uniform Refinement Property for Congruence Lattices
The Congruence Lattice Problem asks whether every algebraic distributive lattice is isomorphic to the congruence lattice of a lattice. It was hoped that a positive solution would follow from E. T. Schmidt’s construction or from the approach of P. Pudlák, M. Tischendorf, and J. Tůma. In a previous paper, we constructed a distributive algebraic lattice A with א2 compact elements that cannot be ob...
متن کاملShimura curves with many uniform dessins
A compact Riemann surface of genus g > 1 has different uniform dessins d’enfants of the same type if and only if its surface group S is contained in different conjugate Fuchsian triangle groups ∆ and α∆α. Tools and results in the study of these conjugates depend on whether ∆ is an arithmetic triangle group or not. In the case when ∆ is not arithmetic the possible conjugators are rare and easy t...
