Beta Function , C – Theorem and WDVV Equations in 4 D N = 2 SYM

چکیده
We show that the exact beta–function of 4D N = 2 SYM plays the role of the inverse of the metric in the WDVV–like equations F ikl β lm F mnj = F jkl β lm F mni. The conjecture that the WDVV–like equations are equivalent to the identity between the u–modulus and the prepotential F , seen as a superconformal anomaly, sheds light on the recently considered C–theorem for the N = 2 SYM field theories.

SYM RG Scale as Modulus for WDVV Equations
We derive a new set of WDVV equations for N = 2 SYM in which the renormalization scale Λ is identified with the distinguished modulus which naturally arises in topological field theories.
متن کاملRG Flow Irreversibility , C - Theorem and Topological Nature of 4 D N = 2 SYM
We determine the exact beta function and a RG flow Lyapunov function for N = 2 SYM with gauge group SU(n). It turns out that the classical discriminants of the Seiberg–Witten curves determine the RG potential. The radial irreversibility of the RG flow in the SU(2) case and the non–perturbative identity relating the u–modulus and the superconformal anomaly, indicate the existence of a four dimen...
متن کاملThe existence results for a coupled system of nonlinear fractional differential equations with multi-point boundary conditions
In this paper, we study a coupled system of nonlinear fractional differential equations with multi-point boundary condi- tions. The differential operator is taken in the Riemann-Liouville sense. Applying the Schauder fixed-point theorem and the contrac- tion mapping principle, two existence results are obtained for the following system D^{alpha}_{0+}x(t)=fleft(t,y(t),D^{p}_{0+}y(t)right), t in (0,...
متن کاملNonperturbative Relations in N=2 Susy Yang-mills and Wdvv Equation
We obtain the nonperturbative relation v = ± 2 3 √ 3 u + cΛF12 + dΛ. This relation gives 〈trφ3〉 in terms of the prepotential F and the vevs 〈φi〉 in N = 2 SYM with gauge group SU(3). We also obtain the nonlinear differential equations satisfied by F and show that these include the Witten – Dijkgraaf – Verlinde – Verlinde equation. The method we propose can be generalized to higher rank groups. P...
متن کاملOne-Instanton Prepotentials From WDVV Equations in N = 2 Supersymmetric SU(4) Yang-Mills Theory
Prepotentials in N = 2 supersymmetric Yang-Mills theories are known to obey non-linear partial differential equations called Witten-Dijkgraaf-Verlinde-Verlinde (WDVV) equations. In this paper, the prepotentials at one-instanton level in N = 2 supersymmetric SU(4) Yang-Mills theory are studied from the standpoint of WDVV equations. Especially, it is shown that the one-instanton prepotentials are...
