New results include: an operator formulation of the covariant interacting string field theory of Witten the string and nonlinear sigma model connection; Kac-Moody and Virasoro algebras and their applications to string theories; compactified strings on group manifold as non-linear sigma models with Wess-Zumino terms and BRST quantization simplicial lattice formulation of gravity and strings; numerical studies of Polyakov strings and their Hausdorff dimensions; stability of vacuum energies for strings compactified on various tori; tests for topological features of string interactions for hadronic processes. Studies in strong coupling phenomena and the continuum description by the technique of infrared extraction, the structure of non-semisimple gauge theories and contracted gauge theories have been continued. Problems associated with the family structure of quarks and leptons, and the interface between cosmology and the grand unification of particle interactions have also been addressed: predictions on the fourth generation quarks; gauge model of fermion flavors and breaking patterns at axion scale; massive neutrinos and oscillations calculability problem in flavor mixings; axion emission for representative types of stars.

It is useful to employ the formalism in terms of currents, and then one is able to restore the continuous symmetries which, according to general theorems, cannot be spontaneously broken at the full quantum level. As a prototype example we consider in detail the non-linear Schrodinger theory at finite density. Some observations concerning theories with non-Abelian symmetry are made.

A detailed comparison with other approaches, especially with the collective coordinate method is made. As an example we also discuss the four-dimensional Yang-Mills pseudoparticle solution.

Interestingly the hamiltonian for the bilocal collective field is the same as that of the O(N) model. However, the large-N saddle points of the two models differ by a sign. This leads to a fluctuation hamiltonian with a negative quadratic term and alternating signs in the nonlinear terms which correctly reproduces the correlation functions of the singlet sector. Assuming the validity of the connection between O(N) collective fields and higher spin fields in AdS, we argue that a natural interpretation of this theory is by a double analytic continuation, leading to the dS/CFT correspondence proposed by Anninos, Hartman and Strominger. The bi-local construction gives a map into the bulk of de Sitter space-time. Its geometric pseudospin-representation provides a framework for quantization and definition of the Hilbert space. We argue that this is consistent with finite N grassmanian constraints, establishing the bi-local representation as a nonperturbative framework for quantization of Higher Spin Gravity in de Sitter space.

We show how this bilocal field can be decomposed into an infinite number of even spin fields in one more dimension. The collective field has a nontrivial classical solution which leads to a O(N ) thermodynamic entropy characteristic of the lower dimensional theory, as required by general considerations of holography. A subtle cancellation of the entropy coming from the bulk fields in one higher dimension with O(1) contributions from the classical solution ensures that the subleading terms in thermodynamic quantities are of the expected form. While the spin components of the collective field transform properly under dilatational, translational and rotational isometries of AdS, special conformal transformations mix fields of different spins indicating a need for a nonlocal map between the two sets of fields. We discuss the nature of the propagating degrees of freedom through a hamiltonian form of collective field theory and argue that nonsinglet states which are present in an euclidean version are related to nontrivial backgrounds.

We construct their Yangian-su(R) invariant Hamiltonian. It describes an interacting theory of a c = 1 collective boson and a k = 1 su(R) current algebra. When R ≥ 3 cubic-current terms arise. Their coupling is determined by the requirement of the Yangian symmetry. The Hamiltonian can be consistently reduced to finite-dimensional subspaces of states, enabling an explicit computation of the spectrum which we illustrate in the simplest case.

We apply it to study the continuous Heisenberg spin chain, which has been known to possess interesting classical solutions. The calculated semi-classical spectrum turns out to be essentially exact. We also construct a new infinite series of conservation laws that are nonlocal generalizations of the spin.

In particular, we derive a constraint which allows us to choose solutions of the classical field equations which directly give the correlation functions of N+ co quantum system. Models studied here include quantum mechanics on a sphere, two-dimensional linear and nonlinear O(N) field theories and the Cy model.
