Chiral Polyhedra in Ordinary Space, I

Chiral polyhedra in ordinary euclidean space E3 are nearly regular polyhedra; their geometric symmetry groups have two orbits on the flags, such that adjacent flags are in distinct orbits. This paper completely enumerates the discrete infinite chiral polyhedra in E3 with finite skew faces and finite skew vertex-figures. There are several families of such polyhedra of types {4, 6}, {6, 4} and {6...

Chiral Gauge Theories in the Overlap Formalism

The overlap formula for the chiral determinant is presented and the realization of gauge anomalies and gauge field toplogy in this context is discussed. The ability of the overlap formalism to deal with supersymmetric theories and Majorana-Weyl fermions is outlined. Two applications of the overlap formalism are discussed in some detail. One application is the computation of a fermion number vio...

D-Branes in Curved Space

We review recent work on the structure of the action forN D0-branes in a curved background, with emphasis on the meaning of space-time diffeomorphism invariance. Talk given at the Francqui Colloquium, 2001, “Strings and Gravity: Tying the Forces Together.” E-mail: [email protected] Since their introduction in 1995 [1], D-branes have played a tremendously important role in string theory. It...

D-Branes in Curved Space

We obtain actions for N D-branes occupying points in a manifold with arbitrary Kähler metric. In one complex dimension, the action is uniquely determined (up to second order in commutators) by the requirement that it reproduce the masses of stretched strings and by imposing supersymmetry. These conditions are very restrictive in higher dimensions as well. The results provide a noncommutative ex...

Chiral Dynamics and Heavy-Fermion Formalism in Nuclei: I. Exchange Axial Currents

Chiral perturbation theory in heavy-fermion formalism is developed for meson-exchange currents in nuclei and applied to nuclear axial-charge transitions. Cal-culation is performed to the next-to-leading order in chiral expansion whichinvolves graphs up to one loop. The result turns out to be very simple. Thepreviously conjectured notion of “chiral filter mechanism” in the ti...
