Preprint “Special functions of hypercomplex variable on the lattice based on SU(1,1)”

Based on the representation of a set of canonical operators on the lattice h\mathbb{Z}^n, which are Clifford-vector-valued, we will introduce new families of special functions of hypercomplex variable possessing \mathfrak{su}(1,1) symmetries. The Fourier decomposition of the space of Clifford-vector-valued polynomials with respect to the SO(n)\times \mathfrak{su}(1,1)– module gives rise to the construction of new families of polynomial sequences as eigenfunctions of a coupled system involving forward/backward discretizations E_h^{\pm} of the Euler operator E=\sum_{j=1}^nx_j \partial_{x_j}.

Moreover, the interpretation of the one-parameter representation \mathbb{E}_h(t)=\exp(tE_h^--tE_h^+) of the Lie group SU(1,1) as a semigroup \left(\mathbb{E}_h(t)\right)_{t\geq 0} will allows us to describe the polynomial solutions of a homogeneous Cauchy problem on [0,\infty)\times h\mathbb{Z}^n involving the differencial-difference operator \partial_t+E_h^+-E_h^-.

Discrete Clifford Analysis (2009-2013).

This thesis studies the fundamentals of a higher dimensional discrete function
theory using the Clifford Algebra setting. This approach combines the ideas of
Umbral Calculus and Differential Forms. Its powerful rests mostly on the
interplay between both languages. This allowed the construction of intertwining
operators between continuous and discrete structures, lifting the well known
results from continuum to discrete.
Furthermore, this resulted in a mimetic transcription of basis polynomial,
generating functions, Fischer Decomposition, Poincaré and dual-Poincaré
lemmata, Stokes theorem and Cauchy’s formula.
This theory also includes the description discrete counterparts of differential
forms, vector-fields and discrete integration. Indeed the resulted construction of
discrete differential forms, discrete vector-fields and discrete integration in
terms of barycentric coordinates leads to the correspondence between the
theory of Finite Differences and the theory of Finite Elements, which gives a
core of promising applications of this approach in numerical analysis. Some
preliminary ideas on this point of view were presented in this thesis.
We also developed some preliminary results in the theory of discrete
monogenic functions on simplicial complexes. Some connections with
Combinatorics and Quantum Mechanics were also presented along this thesis.

Abstract of my dissertation which provides me the doctor degree in mathematics (March 26, 2009).  In a couple of weeks I wish to disseminate some new material with the goal to continue developing the discrete Clifford analysis arena.

The dissemation of new material likewise some ongoing research around was the main motivation to create this blog. In a nearly future, I wish to create a research networking project within this topic with the goal to promote research discussions around this topic.  If you are still interested in join in, please feel it free to send me an e-mail.

Call for papers for 100th Volume – Vacuum

The journal Vacuum is approaching a new landmark. Having started publication in 1952, we will publish Vacuum’s 100th volume this autumn. An event we want to mark by making this a special volume.

Volume 100 will be an open access volume, freely available to everyone, and providing the papers with maximum exposure. Long-time Editor, Prof. John Colligon, has agreed to write an article on the history of the journal.

In addition, we would like to invite you to contribute a Rapid Communication to Volume 100. Vacuum has recently introduced a Rapid Communication section for short papers that will be reviewed promptly. The articles have to fit the guidelines and contain new data worthy of rapid communication.

Rapid Communication contributions that we receive before June 15, 2013 will be considered for Volume 100. Please join us in celebrating!  Submit your best work and receive maximum exposure! We look forward to receiving your manuscripts.
