Vertex Representations via Finite Groups and the Mckay Correspondence
where the first factor is a symmetric algebra and the second one is a group algebra. The affine algebra ĝ contains a Heisenberg algebra ĥ. One can define the so-called vertex operators X(α, z) associated to α ∈ Q acting on V essentially using the Heisenberg algebra ĥ. The representation of ĝ on V is then obtained from the action of the Heisenberg algebra ĥ and the vertex operators X(α, z) assoc...
متن کاملTwisted Vertex Representations via Spin Groups and the Mckay Correspondence
We establish a twisted analog of our recent work on vertex representations and the McKay correspondence. For each finite group Γ and a virtual character of Γ we construct twisted vertex operators on the Fock space spanned by the super spin characters of the spin wreath products Γ ≀ S̃n of Γ and a double cover of the symmetric group Sn for all n. When Γ is a subgroup of SL2(C) with the McKay virt...
متن کاملQuantum Vertex Representations via Finite Groups and the Mckay Correspondence
We establish a q-analog of our recent work on vertex representations and the McKay correspondence. For each finite group Γ we construct a Fock space and associated vertex operators in terms of wreath products of Γ×C and the symmetric groups. An important special case is obtained when Γ is a finite subgroup of SU2, where our construction yields a group theoretic realization of the representation...
متن کاملGauge-covariant vertex operators
We derive Yang-Mills vertex operators for (super)string theory whose BRST invariance requires only the free gauge-covariant field equation and no gauge condition. Standard conformal field theory methods yield the three-point vertices directly in gauge-invariant form. E-mail address: [email protected] E-mail address: [email protected]
متن کاملExts and Vertex Operators
The direct product of two Hilbert schemes of the same surface has natural K-theory classes given by the alternating Ext groups between the two ideal sheaves in question, twisted by a line bundle. We express the Chern classes of these virtual bundles in terms of Nakajima operators.
