Matrix coordinate transformations are defined as substitution operators without requiring an ordering prescription or an inclusion function from the Abelian coordinate transformations. We construct transforming objects mimicking most of the propertie

The limiting procedure of special Kahler manifolds to their rigid limit is studied for moduli spaces of Calabi-Yau manifolds in the neighbourhood of certain singularities. In two examples we consider all the periods in and around the rigid limit, ide

We show that the classical equation of motion of a radiating charged point particle (the Lorentz-Dirac equation) has ``tunneling'' solutions. For a given initial position and velocity we find that, contrary to common belief, several different physica

The phase space of a particle on a group manifold can be split in left and right sectors, in close analogy with the chiral sectors in Wess Zumino Witten models. We perform a classical analysis of the sectors, and the geometric quantization in the cas

To any non-trivial embedding of sl(2) in a (super) Lie algebra, one can associate an extension of the Virasoro algebra. We realize the extended Virasoro algebra in terms of a WZW model in which a chiral, solvable group is gauged, the gauge group bein

As a preparation for the study of {\it arbitrary} extensions of $d=2$ gravity we present a detailed investigation of $SO(N)$ supergravity. By gauging a chiral, nilpotent subgroup of the $OSp(N|2)$ Wess-Zumino-Witten model we obtain an all order expre

The Jacobian for infinitesimal BRST transformations of path integrals for pure Yang-Mills theory, viewed as a matrix $\unity +\Delta J$ in the space of Yang-Mills fields and (anti)ghosts, contains off-diagonal terms. Naively, the trace of $\Delta J$

The generalized Virasoro construction is extended to affine Lie Superalgebras. An analogue to the Super Sugawara construction is found for non-semisimple U(1|1). The resulting master equations are completely solved for SU(2|1) also. Several new solut

We present new superconformal algebras, containing both bosonic and fermionic supersymmetries, based on the superalgebras OSp(m|2n) and U(m|n). They contain as special cases the previously known series based on O( m ), U( m ) and Sp(2 n ) Lie algebra

The first three leading terms of the asymptotic form of the scattering amplitude for the n -rung 3 ladder diagram in six dimensions are derived in the high-energy, large-momentum transfer limit. The behavior of these terms is qualitatively different
