In this talk we will summarise a systematic approach to constructing physical, i.e., gauge-invariant, fields describing charged particles. We will show that this can be done in a well defined way in abelian theories and perturbatively in non-abelian

A crucial element of scattering theory and the LSZ reduction formula is the assumption that the coupling vanishes at large times. This is known not to hold for the theories of the Standard Model and in general such asymptotic dynamics is not well und

The quarks of quark models cannot be identified with the quarks of the QCD Lagrangian. We review the restrictions that gauge field theories place on any description of physical (colour) charges. A method to construct charged particles is presented. T

We investigate the cohomology groups H 1 ( Z , O ( L ⊗ m )), where Z is the twistor space of a compact quaternionic-Kahler manifold M , of dimension 4 k , for k ⩾ 1, L is the holomorphic contact line bundle on Z , and m ⩾ 0. The Penrose transfo

In Twistor Conformal Field Theory the Riemann surfaces and holomorphic functions of two-dimensional conformal field theory are replaced by “flat” twistor spaces (arising from conformally-flat four-manifolds) and elements of the holomorphic first

An efficient algorithm to count all codewords of given weight and a method to deduce the modular congruence of the weight distributions of the binary quadratic double-circulant codes are presented. Using this algorithm, we give the weight distributio

This paper presents a more efficient algorithm to count codewords of given weights in self-dual double-circulant and formally self-dual quadratic double-circulant codes over GF(2). A method of deducing the modular congruence of the weight distributio

The reduced Hamiltonian system on T*SU(3)/SU(2)) is derived from a Riemannian geodesic motion on the SU(3) group manifold parameterised by the generalised Euler angles and endowed with a bi-invariant metric. Our calculations show that the metric defi

A new method of finding binary cyclic codes from the finite-field transform domain is presented. These cyclic codes have sparse parity-check matrix and thus are suitable for iterative decoding. Some interesting properties of the proposed construction
