Polyharmonic and Related Kernels on Manifolds: Interpolation and Approximation

open access: yes, 2011
This article is devoted to developing a theory for effective kernel interpolation and approximation in a general setting. For a wide class of compact, connected $C^\infty$ Riemannian manifolds, including the important cases of spheres and SO(3), we ...

Output controllability of impulsive Boolean control networks based on hybrid‐index model

open access: yesIET Control Theory &Applications, Volume 18, Issue 6, Page 738-747, April 2024.
By resorting to the tool of semi‐tensor product, this study investigates the output controllability of Boolean control networks with state‐triggered impulses, which is an important model for describing gene regulatory networks. Compared with the time or event‐based impulse triggering models, the hybrid‐index model employed in this paper is more helpful

A survey on applications of the semi‐tensor product method in Boolean control networks with time delays

open access: yesEngineering Reports, Volume 6, Issue 1, January 2024.
This paper provides a comprehensive knowledge overview of Boolean networks with time delays (TBN) via the semi‐tensor product theory (STP), which includes the history of BNs, the property of STP, several issues of TBNs, and future prospects. The related problems contain controllability and reachability, observability and detectability, stability, and ...

Supersymmetric Drinfeld-Sokolov reduction

open access: yes, 1998
The Drinfeld-Sokolov construction of integrable hierarchies, as well as its generalizations, may be extended to the case of loop superalgebras. A sufficient condition on the algebraic data for the resulting hierarchy to be invariant under supersymmetry ...

Representation theory of finite W algebras

open access: yes, 1992
In this paper we study the finitely generated algebras underlying $W$ algebras. These so called 'finite $W$ algebras' are constructed as Poisson reductions of Kirillov Poisson structures on simple Lie algebras.

Globally conformal invariant gauge field theory with rational correlation functions

open access: yes, 2003
Operator product expansions (OPE) for the product of a scalar field with its conjugate are presented as infinite sums of bilocal fields V_k (x_1, x_2) of dimension (k,k).
