Self-dual Spherical Grids

Self-dual plane graphs have been studied extensively. C. A. B Smith and W. T. Tutte published A class of self-dual maps in 1950 [9]; in 1992, Archdeacon and Richter [1] described a method for constructing all self-dual plane graphs and a second construction was produced by Servatius and Christopher [5] in 1992. Both constructions are inductive. In this paper, we produce four templates from whic...

Finitely semisimple spherical categories and modular categories are self - dual

We show that every essentially small finitely semisimple k-linear additive spherical category in which k = End(1) is a field, is equivalent to its dual over the long canonical forgetful functor. This includes the special case of modular categories. In order to prove this result, we show that the universal coend of the spherical category with respect to the long forgetful functor is self-dual as...

PML-FDTD in Cylindrical and Spherical Grids

Perfectly matched layers (PML’s) are derived for cylindrical and spherical finite-difference time-domain (FDTD) grids. The formulation relies on the complex coordinate stretching approach. Two-dimensional (2-D) cylindrical and three-dimensional (3-D) spherical staggered-grid FDTD codes are written based on the time-domain versions of the equations. Numerical simulations validate the formulation...

Climate modeling with spherical geodesic grids

creasing concentrations of carbon dioxide and greenhouse gases from fossil fuel combustion and other human activities dramatically affect the Earth’s climate, but exactly what changes in climate can we expect in the coming years? What will the impact be, for example, on agriculture, unmanaged ecosystems, and sea levels? Which regions of the world will be most affected? We can’t learn the answer...

Self-dual and quasi self-dual algebras

A self-dual algebra is an associative or Lie algebra A together with an A bimodule isomorphism A → A∨op, where A∨ = Homk(A, k), the dual bimodule to A (considered as an A bimodule), and A∨op is the the same underlying k module as A∨ but is an A bimodule whose left operation by an element a ∈ A is the same as the right operation by a on A∨, and similarly with left and right interchanged. This in...
