Question on D=26 --- String Theory versus Quantum Gravity ---
Mitsuo Abe, Noboru Nakanishi
In the covariant-gauge two-dimensional quantum gravity, various derivations of the critical dimension D=26 of the bosonic string are critically reviewed, and their interrelations a…
Proof of the Gauge Independence of the Conformal Anomaly of Bosonic String in the Sense of Kraemmer and Rebhan
Mitsuo Abe, Noboru Nakanishi
Kraemmer and Rebhan claimed the gauge independence of the conformal anomaly of bosonic string for various gauge fixings in the framework of the perturbation theory of two-dimension…
Quantized Affine Algebras and Crystals with Head
Seok-Jin Kang, Masaki Kashiwara
Motivated by the work of Nakayashiki on the inhomogeneous vertex models of 6-vertex type, we introduce the notion of crystals with head. We show that the tensor product of the high…
On fibre space structures of a projective irreducible symplectic manifold
Daisuke Matsushita
In this note, we investigate fibre space structures of a projective irreducible symplectic manifold. We prove that an 2n-dimensional projective irreducible symplectic manifold admi…
Form factors of the XXZ model and the affine quantum group symmetry
Yas-Hiro Quano
We present new expressions of form factors of the XXZ model which satisfy Smirnov's three axioms. These new form factors are obtained by acting the affine quantum group $U_q (\hat{…
The decomposition of level-1 irreducible highest weight modules with respect to the level-0 actions of the quantum affine algebra
Kouichi Takemura
We decompose the level-1 irreducible highest weight modules of the quantum affine algebra with respect to the level-0 --action defined in q-alg…
The Monodromy Matrices of the XXZ Model in the Infinite Volume Limit
Tetsuji Miwa, Robert Weston
We consider the XXZ model in the infinite volume limit with spin half quantum space and higher spin auxiliary space. Using perturbation theory arguments, we relate the half infinit…
Infinitesimal Takesaki duality of Hamiltonian vector fields on a symplectic manifold
Katsunori Kawamura
For an infinitesimal symplectic action of a Lie algebra ${\goth g}$ on a symplectic manifold, we construct an infinitesimal crossed product of Hamiltonian vector fields and Lie alg…
Dispersionless Hierarchies, Hamilton-Jacobi Theory and Twistor Correspondences
Partha Guha, Kanehisa Takasaki
The dispersionless KP and Toda hierarchies possess an underlying twistorial structure. A twistorial approach is partly implemented by the method of Riemann-Hilbert problem. This is…
Anomaly Problem in a Simple Model Analogous to the Lightcone-Gauge Two-Dimensional Quantum Gravity
Mitsuo Abe, Noboru Nakanishi
It was found in the two-dimensional quantum gravity both in the de Donder gauge and in the lightcone gauge that one of field equations breaks down at the level of the representatio…
Yangian Gelfand-Zetlin Bases, gl(N)-Jack Polynomials and computation of Dynamical Correlation Functions in the Spin Calogero-Sutherland Model
Denis Uglov
We consider the gl(N)-invariant Calogero-Sutherland Models with N=1,2,3,... in a unified framework, which is the framework of Symmetric Polynomials. By the framework we mean an iso…
Graphical Classification of Global SO(n) Invariants and Independent General Invariants
Shoichi Ichinose, Noriaki Ikeda
This paper treats some basic points in general relativity and in its perturbative analysis. Firstly a systematic classification of global SO(n) invariants, which appear in the weak…
Spontaneous Collapse of Supersymmetry
Detlev Buchholz, Izumi Ojima
It is shown that, if generators of supersymmetry transformations (supercharges) can be defined in a spatially homogeneous physical state, then this state describes the vacuum. Thus…
Separation of variables for the Ruijsenaars system
V. B. Kuznetsov, F. W. Nijhoff, E. K. Sklyanin
We construct a separation of variables for the classical n-particle Ruijsenaars system (the relativistic analog of the elliptic Calogero-Moser system). The separated coordinates ap…
The Yangian Symmetry in the Spin Calogero Model and its Applications
Kouichi Takemura
By using the non-symmetric Hermite polynomials and a technique based on the Yangian Gelfand-Zetlin bases, we decompose the space of states of the Calogero model with spin into irre…
