We describe in brief some aspects of the Langlands program, focussing on Euler products, and also some new constructions, where Euler products are replaced by twisted Euler products. The twisted Euler products are related to automorphic forms on metaplectic groups. 2000 Mathematics Subject Classification: 11F66, 11F55, 11F70, 11M41, 22E55.

We consider a topological integral transform of Bessel (concentric isospectral sets) type and Fourier (hyperplane isospectral sets) type, using the Euler characteristic as a measure. These transforms convert constructible Z-valued functions to continuous R-valued functions over R n. Core contributions include: the definition of the topological Bessel transform; a relationship in terms of the lo...

In this short paper we generalize some previous results on attitude representations using higher order Cayley transforms. We show that the kinematic parameters generated by these higher order Cayley transforms have a a very simple limit, i.e., the well-known Euler vector. Introduction In a recent paper1 we introduced the concept of Higher Order Cayley Transforms (HOCT) as a means of generating ...

A lattice model of critical dense polymers is solved exactly for finite strips. The model is the first member of the principal series of the recently introduced logarithmic minimal models. The key to the solution is a functional equation in the form of an inversion identity satisfied by the commuting double-row transfer matrices. This is established directly in the planar Temperley-Lieb algebra...

The interaction of a plane acoustic wave and a sheared flow is numerically investigated for simple orifice and perforated plate configurations in an isolated, non-resonant environment for Mach numbers up to choked conditions in the holes. Analytical derivations found in the literature are not valid in this regime due to restrictions to low Mach numbers and incompressible conditions. To allow fo...

The Wigner D-functions, D pq(α,β, γ ), are known for their frequent use in quantum mechanics. Defined as the matrix elements of the rotation operator R̂(α,β, γ ) in R3 and parametrized in terms of the three Euler angles α, β, and γ , these functions arise not only in the transformation of tensor components under the rotation of the coordinates, but also as the eigenfunctions of the spherical top...

A new grid method for computing the Snell envelop of a function of a R d -valued Markov chain (Xk)0≤k≤n is proposed. (This problem is typically non linear and cannot be solved by the standard Monte Carlo method.) Every Xk is replaced by a “quantized approximation” X̂k taking its values in a grid Γk of size Nk. The n grids and their transition probability matrices make up a discrete tree on which...

A new combinatorial characterization of a gray-tone image called Euler Vector is proposed. Euler number of a binary image is a well-known topological feature, which remains invariant under translation, rotation, scaling, and rubber-sheet transformation of the image. Euler vector comprises of a 4-tuple, where each element is an integer representing the Euler number of the partial binary image fo...
