The Orbifold Topological Vertex
We define Donaldson-Thomas invariants of Calabi-Yau orbifolds and we develop a topological vertex formalism for computing them. The basic combinatorial object is the orbifold vertex V λμν , a generating function for the number of 3D partitions asymptotic to 2D partitions λ, μ, ν and colored by representations of a finite Abelian group G acting on C. In the case where G ∼= Zn acting on C with tr...
متن کاملThe Topological Vertex
We construct a cubic field theory which provides all genus amplitudes of the topological A-model for all non-compact toric Calabi-Yau threefolds. The topology of a given Feynman diagram encodes the topology of a fixed Calabi-Yau, with Schwinger parameters playing the role of Kähler classes of the threefold. We interpret this result as an operatorial computation of the amplitudes in the B-model ...
متن کاملDonaldson-thomas Invariants of Local Elliptic Surfaces via the Topological Vertex
We compute the Donaldson-Thomas invariants of a local elliptic surface with section. We introduce a new computational technique which is a mixture of motivic and toric methods. This allows us to write the partition function for the invariants in terms of the topological vertex. Utilizing identities for the topological vertex proved in [4], we derive product formulas for the partition functions....
متن کاملOn a Deformed Topological Vertex
Recall the topological vertex involves three partitions, when one of them is empty it is related to the leading term of the large N colored HOMFLY polynomials of the Hopf link, and the general topological vertex can be expressed in terms of such leading terms. We will use the whole colored HOMFLY polynomials to define the deformed vertex, hence deformations of the partition functions of topolog...
متن کاملAn Elliptic Current Operator for the Eight Vertex Model
Whereas the tools to determine the eigenvalues of the eight-vertex transfer matrix T are well known there has been until recently incomplete knowledge about the eigenvectors of T. We describe the construction of eigenvectors of T corresponding to degenerate eigenvalues and discuss the related hidden elliptic symmetry.
