On non-conformal limit of the AGT relations
The Seiberg-Witten prepotentials for N = 2 SUSY gauge theories with Nf < 2Nc fundamental multiplets are obtained from conformalNf = 2Nc theory by decoupling 2Nc−Nf multiplets of heavy matter. This procedure can be lifted to the level of Nekrasov functions with arbitrary background parameters ǫ1 and ǫ2. The AGT relations imply that similar limit exists for conformal blocks (or, for generic Nc > ...
متن کاملConformal invariance from non-conformal gravity
We discuss the conditions under which classically conformally invariant models in four dimensions can arise out of non-conformal (Einstein) gravity. As an ‘existence proof’ that this is indeed possible we show how to derive N = 4 super Yang Mills theory with any compact gauge group G from non-conformal gauged N = 4 supergravity as a special flat space limit. We stress the role that the anticipa...
متن کاملTorus Knots Extremizing the Conformal Energy
A useful geometric property of E is conformal invariance: if μ is a Möbius transformation of R ∪∞, and μ(Γ) ⊂ R, then E(μ(Γ)) = E(Γ). This can be used to prove [FHW] that each prime knot class has an energy minimizing representative (of differentiability class C), and that the round circle is the unique energy minimizer among all curves (E = 4). It is also a non-trivial result of [FHW] that, at...
متن کامل1 SUSY Conformal Block Recursive Relations
We present explicit recursive relations for the four-point superconformal block functions that are essentially particular contributions of the given conformal class to the four–point correlation function. The approach is based on the analytic properties of the superconformal blocks as functions of the conformal dimensions and the central charge of the superconformal algebra. The results are com...
متن کاملNewtonian limit of conformal gravity
We study the weak-field limit of the static spherically symmetric solution of the locally conformally invariant theory advocated in the recent past by Mannheim and Kazanas as an alternative to Einstein’s General Relativity. In contrast with the previous works, we consider the physically relevant case where the scalar field that breaks conformal symmetry and generates fermion masses is nonzero. ...
