On Hyperkahler Singularities

چکیده
Using a geometric realization of the SU(2)R symmetry and a procedure of factorisation of the gauge and SU(2)R charges, we study the small instanton singularities of the Higgs branch of supersymmetric U(1) gauge theories with eight supercharges. We derive new solutions for the moduli space of vacua preserving manifestly the eight supercharges. In particular, we obtain an extension of the ordinary ADE singularities for hyperKahler manifolds and show that the classical moduli space of vacua is in general given by cotangent bundles of compact weighted projective spaces. ∗ [email protected] † [email protected]

Integrating over Higgs Branches
We develop some useful techinques for integrating over Higgs branches in supersymmetric theories with 4 and 8 supercharges. In particular, we define a regularized volume for hyperkahler quotients. We evaluate this volume for certain ALE and ALF spaces in terms of the hyperkahler periods. We also reduce these volumes for a large class of hyperkahler quotients to simpler integrals. These quotient...
متن کاملHyperkahler Singularities in Superstrings Compactification and 2 d N = 4 Conformal Field Theory
We study the singularities of the Higgs branch of supersymmetric U (1) r gauge theories with eight supercharges. We derive new solutions for the mod-uli space of vacua preserving manifestly the eight supercharges by using a geometric realization of the SU (2) R symmetry and a separation procedure of the gauge and SU (2) R charges, which allow us to put the hypermultiplet vacua in a form dependi...
متن کاملHeterotic geometry without isometries
We present some properties of hyperkahler torsion (or heterotic) geometry in four dimensions that make it even more tractable than its hyperkahler counterpart. We show that in d = 4 hypercomplex structures and weak torsion hyperkahler geometries are the same. We present two equivalent formalisms describing such spaces, they are stated in the propositions of section 1. The first is reduced to so...
متن کاملRings of Singularities
This paper is a slightly revised version of an introduction into singularity theory corresponding to a series of lectures given at the ``Advanced School and Conference on homological and geometrical methods in representation theory'' at the International Centre for Theoretical Physics (ICTP), Miramare - Trieste, Italy, 11-29 January 2010. We show how to associate to a triple of posit...
متن کاملThe ADHM Construction and Anselmi’s Topological Anomalies
We examine the anomalies arising in instanton calculus as detailed by Damiano Anslemi in 1994. Whereas Anselmi uses BRST theory, we use the ADHM construction to arrive at the same conclusions from a differentialgeometric way. We observe that Anselmi’s TQFT is similar to Donaldson Theory applied to charge 1 instantons on the 4-sphere,although the latter is really only used for 4-manifolds with b...
