Rational maps and string topology [PDF]
Geometry & Topology, 2006 We apply a version of the Chas-Sullivan-Cohen-Jones product on the higher loop homology of a manifold in order to compute the homology of the spaces of continuous and holomorphic maps of the Riemann sphere into a complex projective space. This product makes sense on the homology of maps from a co-H space to a manifold, and comes from a ring spectrum ...

Bethe/Gauge correspondence in odd dimension: modular double, non-perturbative corrections and open topological strings [PDF]
, 2016 A bstractBethe/Gauge correspondence as it is usually stated is ill-defined in five dimensions and needs a “non-perturbative” completion; a related problem also appears in three dimensions.

Geometry and Topology of String Junctions [PDF]
Journal of Singularities, 2016 We study elliptic fibrations by analyzing suitable deformations of the fibrations and vanishing cycles. We introduce geometric string junctions and describe some of their properties. We show how the structure of the geometric string junctions is naturally related to the Lie algebra structures of the associated singularities.

Universal character, phase model and topological strings on $$\pmb {\mathbb {C}^3}$$ [PDF]
The European Physical Journal C, 2017 In this paper, we consider two different subjects: the algebra of universal characters$$S_{[\lambda ,\mu ]}(\mathbf{x},\mathbf{y})$$S[λ,μ](x,y)(a generalization of Schur functions) and the phase model of strongly correlated bosons.

Tackling tangledness of cosmic strings by knot polynomial topological invariants
, 2016 Cosmic strings in the early universe have received revived interest in recent years. In this paper we derive these structures as topological defects from singular distributions of the quintessence field of dark energy.

Membranes for Topological M-Theory
, 2005 We formulate a theory of topological membranes on manifolds with G_2 holonomy. The BRST charges of the theories are the superspace Killing vectors (the generators of global supersymmetry) on the background with reduced holonomy G_2.

ABCD of Beta Ensembles and Topological Strings [PDF]
, 2012 We study beta-ensembles with Bn, Cn, and Dn eigenvalue measure and their relation with refined topological strings. Our results generalize the familiar connections between local topological strings and matrix models leading to An measure, and illustrate ...

String topology on Gorenstein spaces [PDF]
Mathematische Annalen, 2009 The purpose of this paper is to describe a general and simple setting for defining $(g,p+q)$-string operations on a Poincar duality space and more generally on a Gorenstein space. Gorenstein spaces include Poincar duality spaces as well as classifying spaces or homotopy quotients of connected Lie groups.

Stable vs Unstable Vortices in SQCD
, 2005 We give a topological classification of stable and unconfined massive particles and strings (and some instantons) in worldvolume theories of M5-branes and their dimensional reductions, generalizing Witten's classification of strings in SYM. In particular
