We investigate vacuum expectation values of Wilson loop operators in 2+1 dimensional Chern-Simons theory with compact and simple gauge groups. Owing to the close relationship between the rational conformal field theories and the Chern-Simons theories, we can construct algebraic equations among vacuum expectation values of various Wilson loop operators. These equations are solved exactly. This method could be applicable also for the supersymmetric Chern-Simons theories.

Carrying out a cluster expansion around the two-dimensional lattice topological field theories, we show that a two-dimensional'lattice topological field theory with n physical observables is on a multiple first order phase transition point, around which there are n different phases. This fact is also shown in the context of the twisted N=2 Landau-Ginzburg model.

We investigate the Ward identities of the Wco symmetry in the Liouville theory coupled to the (p, q) minimal matter. It is found that the Ward identities are equivalent to the Wg algebra conditions on the exponential of the partition function.

It is shown that correlation functions of integrable lattice model satisfmg the Yang-Baxter equation, the unitarity and the crossing symmetry, obey a system of difference equations. In particular, the one-point function of the Z_n-Baxter model in the principal regime is obtained as a solution of the simplest difference equation.

We find a quantum group structure in two-dimensional motion of the nonrelativistic electron in a uniform magnetic field. A recombination of the W_∞ algebra enables us to define the quantum algebra of which deformation parameter is given by some physical quantities. The obtained quantum algebra commutes with the Hamiltonian and is relevalnt to the degenerate Landau level.

We demonstrate an explicit evaluation of the traces of the type I q-vertex operators over the irreducible highest weight representation space of the quantum affine algebra U_q(sl_2) with an arbitrary representation level k. The same technique can be applied to the traces of the type II q-vertex operators, which was recently realized by the author. This makes possible the calculation of various form factors in the XXZ and its higher spin extension.

Beyond the WKB approximation, the stability of the minisuperspace model of the early universe is studied by solving the Wheeler-DeWitt (W-D) equation numerically. We consider a system of Einstein gravity with a scalar field. When we solve the W-D equation, we pick up some inhomogeneous wave modes from the infinite number of modes adequately: degrees of freedom of the superspace are restricted to a finite one. We show that the minisuperspace is stable when a scale factor (a) of the universe is larger than a few times of the Planck length, while it becomes unstable when a is comparable to the Planck length. This result agrees with the validity region in which the WKB approximation applicable, although we treat the system beyond it.
