Kodaira-Spencer theory of gravity and exact results for quantum string amplitudes

- M. Bershadsky, S. Cecotti, H. Ooguri, C. Vafa
- Mathematics
- 27 September 1993

We develop techniques to compute higher loop string amplitudes for twistedN=2 theories withĉ=3 (i.e. the critical case). An important ingredient is the discovery of an anomaly at every genus in… Expand

Holomorphic anomalies in topological field theories

- M. Bershadsky, S. Cecotti, H. Ooguri, C. Vafa
- Mathematics
- 20 September 1993

R-Twisting and 4d/2d Correspondences

- S. Cecotti, A. Neitzke, C. Vafa
- Mathematics
- 17 June 2010

We show how aspects of the R-charge of N=2 CFTs in four dimensions are encoded in the q-deformed Kontsevich-Soibelman monodromy operator, built from their dyon spectra. In particular, the monodromy… Expand

GEOMETRY OF TYPE II SUPERSTRINGS AND THE MODULI OF SUPERCONFORMAL FIELD THEORIES

- S. Cecotti, S. Ferrara, L. Girardello
- Mathematics
- 1 June 1989

We study general properties of the low-energy effective theory for 4D type II superstrings obtained by the compactification on an abstract (2,2) superconformal system. This is the basic step towards… Expand

On classification ofN=2 supersymmetric theories

- S. Cecotti, C. Vafa
- Mathematics, Physics
- 1 December 1993

We find a relation between the spectrum of solitons of massiveN=2 quantum field theories ind=2 and the scaling dimensions of chiral fields at the conformal point. The condition that the scaling… Expand

T-branes and monodromy

- S. Cecotti, Clay Córdova, J. Heckman, C. Vafa
- Mathematics
- 27 October 2010

We introduce T-branes, or “triangular branes”, which are novel non-abelian bound states of branes characterized by the condition that on some loci, their matrix of normal deformations, or Higgs… Expand

A New supersymmetric index

- S. Cecotti, P. Fendley, K. Intriligator, C. Vafa
- Mathematics, Physics
- 30 April 1992

$\mathcal{N} = 2$ quantum field theories and their BPS quivers

- M. Alim, S. Cecotti, Clay Córdova, Sam Espahbodi, Ashwin Rastogi, C. Vafa
- Mathematics
- 16 December 2011

We explore the relationship between four-dimensional N = 2 quantum eld theories and their associated BPS quivers. For a wide class of theories including super-Yang-Mills theories, Argyres-Douglas… Expand
