The BRST invariance condition in a highest-weight representation of the topological (≡ twisted N=2) algebra captures the ‘invariant’ content of two-dimensional gravity coupled to matter. The topological algebra allows reductions to either the D

The BRST invariance condition in a highest-weight representation of the topological ($\equiv$ twisted $N=2$) algebra captures the `invariant' content of two-dimensional gravity coupled to matter. The standard DDK formulation is recovered by splitting

The action of the Virasoro algebra on integrable hierarchies of non-linear equations and on related objects (“Schrodinger” differential operators) is investigated. The method consists in pushing forward the Virasoro action to the wave function of

Virasoro constraints on the KP hierarchy, arising in matrix models, are studied by reexpressing them in terms of dressing operators of the hierarchy. There exists a one-parameter family of Virasoro representations on the KP hierarchy (depending on a

I discuss the idea of translating ingredients of conformal field theory into the language of hierarchies of integrable differential equations. Primary conformal fields are mapped into (differential or matrix) operators living on the phase space of th

We apply the global operator bosonization on Riemann surfaces in order to describe the sewing of the bcβγ (reparametrization/superconformal ghosts) theories. The non-trivial part is the βγ sector, where a complicated rearrangement of the structur

The explicit N = 1 supersymmetric coset construction of N = 2 superconformal models due to Kazama and Suzuki can be formulated in terms of free N = 1 superfields using an appropriate superfield version of the Wakimoto bosonization of semi-simple Lie

The recently proposed superbosonization of the bcβγ (ghost-superghost) theory in terms of the ϕ ϕ ψ ψ system is extended to a globally defined operator realization of the ghost-superghost system on higher-genus Riemann surfaces. The bosonizatio

There exist two different languages, the ^sl(2) and N=2 ones, to describe similar structures; a dictionary is given translating the key representation-theoretic terms related to the two algebras. The main tool to describe the structure of ^sl(2) and

A direct relation between the conformal formalism for 2d-quantum gravity and the W-constrained KP hierarchy is found, without the need to invoke intermediate matrix model technology. The Kontsevich-Miwa transform of the KP hierarchy is used to establ
