Introduction Problem Definitions Method Solution Result Supersymmetry is a powerful tool to address dynamics of gauge theories • The N = 2 effective low energy Seiberg-Witten theory • Maldacena’s conjecture on the AdS/CFT correspondence for N = 4 SYM Vasily Pestun Localization for ’t Hooft operators on S 4 2/35
Introduction Problem Definitions Method Solution Result Loop operators are important gauge theory observables. Wilson loop operator measures effective forces between quarks. (locally) supersymmetric Wilson loop operator was the key object in several AdS/CFT studies for N = 4 SYM • [Erickson-Semenoff-Zarembo] and [Drukker-Gross] circular 1/2 BPS Wilson loops in N = 4 SYM • [Alday-Maldacena] polygonal Wilson loops and amplitudes in N = 4 SYM At λ → ∞, Wilson loop C ⊂ R 4 is dual to the minimal surface in AdS landing on C ⊂ R 4 Vasily Pestun Localization for ’t Hooft operators on S 4 3/35
