Wheeler-DeWitt Equation in Two-dimensional Quantum Gravity with Conformal Matter Field
Atushi Ishikawa
In the context of two-dimensional quantum cosmology, we consider the path-integral of a string on annulus which contains the Liouville field and conformal matter fields. We show th…
Rotational Corrections to and Isovector Magnetic Moment of the Nucleon
Chr. V. Christov, K. Goeke, P. Pobilitsa +3
The rotational corrections to the axial vector constant and the isovector magnetic moment of the nucleon are studied in the Nambu -- Jona-Lasinio model. We follow a semicla…
Unstable geodesics and topological field theory
Yukinori Yasui, Satoshi Takahashi
A topological field theory is used to study the cohomology of mapping space. The cohomology is identified with the BRST cohomology realizing the physical Hilbert space and the cobo…
Heavy meson effective thoery with 1/M_Q correction
N. Kitazawa, T. Kurimoto
We construct an effective Lagrangian of heavy and light mesons with correction. The Lagrangian is constructed model independent way by using only the information of the sym…
Quantum Group Symmetry and Quantum Hall Wavefunctions on a Torus
H. -T. Sato
We find a quantum group structure in two-dimensional motion of nonrelativistic electrons in a uniform magnetic field on a torus. The representation basis of the quantum algebra is…
Quantum Group and -Virasoro Current in Fermion Systems
H-T. Sato
We discuss a generalization of the quantum group $\su$ to the -Virasoro algebra in two-dimensional electrons system under uniform magnetic field. It is shown that the integral r…
