Loop operators are important gauge theory observables.<br />
Wilson loop operator measures effective <strong>for</strong>ces between<br />
quarks.<br />
(locally) supersymmetric Wilson loop operator was the key<br />
object <strong>in</strong> several AdS/CFT studies <strong>for</strong> N = 4 SYM<br />
• [Erickson-Semenoff-Zarembo] and [Drukker-Gross] circular<br />
1/2 BPS Wilson loops <strong>in</strong> N = 4 SYM<br />
• [Alday-Maldacena] polygonal Wilson loops and amplitudes<br />
<strong>in</strong> N = 4 SYM<br />
At λ → ∞, Wilson loop C ⊂ R 4 is dual to the m<strong>in</strong>imal surface <strong>in</strong><br />
