Nuclear Physics B, 1994 We show how to make a topological string theory starting from an $N=4$ superconformal theory. The critical dimension for this theory is $\hat c= 2$ ($c=6$).

Topological Strings from WZW Models [PDF]
Physics Letters B, 1994 We show that the BRST structure of the topological string is encoded in the ``small'' $N=4$ superconformal algebra, enabling us to obtain, in a non-trivial way, the string theory from hamiltonian reduction of $A(1|1)$.

Topological strings on noncommutative manifolds [PDF]
International Journal of Geometric Methods in Modern Physics, 2003 We identify a deformation of the N=2 supersymmetric sigma model on a Calabi-Yau manifold X which has the same effect on B-branes as a noncommutative deformation of X.

Topological Strings and Integrable Hierarchies [PDF]
Communications in Mathematical Physics, 2003 We consider the topological B-model on local Calabi-Yau geometries. We show how one can solve for the amplitudes by using W-algebra symmetries which encodes the symmetries of holomorphic diffeomorphisms of the Calabi-Yau.

Topologically Alice Strings and Monopoles [PDF]
Physical Review D, 2003 Symmetry breaking can produce ``Alice'' strings, which alter scattered charges and carry monopole number and charge when twisted into loops. Alice behavior arises algebraically, when strings obstruct unbroken symmetries -- a fragile criterion.

Topological Strings and (Almost) Modular Forms [PDF]
Communications in Mathematical Physics, 2006 The B-model topological string theory on a Calabi-Yau threefold X has a symmetry group Gamma, generated by monodromies of the periods of X. This acts on the topological string wave function in a natural way, governed by the quantum mechanics of the phase

Topological strings on elliptic fibrations [PDF]
Communications in Number Theory and Physics, 2014 We study topological string theory on elliptically fibered Calabi-Yau threefolds using mirror symmetry. We compute higher genus topological string amplitudes and express these in terms of polynomials of functions constructed from the special geometry of the moduli space. The polynomials are fixed by the holomorphic anomaly equations supplemented by the

TOPOLOGICAL ZERO-THICKNESS COSMIC STRINGS [PDF]
Modern Physics Letters A, 2007 In this paper, based on the gauge potential decomposition and the ϕ-mapping theories, we study the topological structures and properties of the cosmic strings that arise in the Abelian–Higgs gauge theory in the zero-thickness limit. After a detailed discussion, we conclude that the topological tensor current introduced in our model is a better and ...

Instantons, Topological Strings, and Enumerative Geometry [PDF]
Advances in Mathematical Physics, 2010 We review and elaborate on certain aspects of the connections between instanton counting in maximally supersymmetric gauge theories and the computation of enumerative invariants of smooth varieties. We study in detail three instances of gauge theories in
