    Materializing superghosts

    The off-shell Batalin-Vilkovysky (BV) realization has been constructed for N = 1, d = 10 super-Yang-Mills theory with seven auxiliary fields. This becomes possible due to the materialized ghost phenomenon. Namely...

    From Zwiebach Invariants to Getzler Relation

    We introduce the notion of Zwiebach invariants that generalize Gromov- Witten invariants and homotopical algebra structures. We outline the induction procedure that induces the structure of Zwiebach invariants...

    Topological quantum mechanics for physicists

    This text is an attempt to write an introduction and outline of main results of topological quantum mechanics for readers with a physical background. Instead of presenting rigorous mathematical formulations, w...

    Extended Modular Operad

    This paper, together with [Ma2], constitutes a sequel to [LoMa] where some new moduli spaces of pointed curves were introduced and studied. We start with a review of the main results of [LoMa] and then give a ...

    Commutativity equations and dressing transformations

    We study dressing transformations that generate all solutions to commutativity equations and, after picking up special coordinates, all solutions to WDVV equations. We conjecture that the homological tensor pr...

    On compatibility of tensor products on solutions to commutativity and WDVV equations

    We show that topological conformal theory contains solutions for WDVV equations for genus zero amplitudes and solutions to Commutativity equations from its quantum mechanics on the annulus. We explain behavior...

    Testing Seiberg-Witten Solution

    One of the sources of the recent duality revolution in string theory is the solution of N. Seiberg and E. Witten [1] of N = 2 supersymmetric Yang-Mills theory which has been tested in many indirect ways but never...

    Central extensions of gauge groups revisited

    We present an explicit construction for the central extension of the group Map(X, G) where X is a compact manifold and G is a Lie group. If X is a complex curve we obtain a simple construction of the extension b...

    On structure and open problems in topological theories coupled to topological gravity

    The structure of topological theory coupled to topological gravity is studied. We show that in this theoryQ-exact terms do not decouple. This nondecoupling in the action of the theory is connected with the existe...
