Children's Drawings From Seiberg-Witten Curves
Sujay K. Ashok, Freddy Cachazo, Eleonora Dell'Aquila
We consider N=2 supersymmetric gauge theories perturbed by tree level superpotential terms near isolated singular points in the Coulomb moduli space. We identify the Seiberg-Witten…
Strebel Differentials With Integral Lengths And Argyres-Douglas Singularities
Sujay K. Ashok, Freddy Cachazo, Eleonora Dell'Aquila
Strebel differentials are a special class of quadratic differentials with several applications in string theory. In this note we show that finding Strebel differentials with integr…
The Topological Cigar Observables
Sujay K. Ashok, Jan Troost
We study the topologically twisted cigar, namely the SL(2,R)/U(1) superconformal field theory at arbitrary level, and find the BRST cohomology of the topologically twisted N=2 theo…
