The aim of the workshop is to bring together researchers working on string field theory, pure spinors, amplitudes and holography to discuss recent developments and to create new collaborations. Recently, many progresses have occurred on these fields such as new vertex operators, new integrable structures, new results in amplitudes and string perturbation theory. String theory is a consistent theory of quantum gravity and it can give us several new insights about it. Moreover, new methods developed originally in string theory can be used to study other conformal theories and gauge theories which have several applications in statistical mechanics, condensed matter and particle physics.


This workshop is jointly organized with the ICTP-Saifr in São Paulo.


The complete event has three weeks in total.


The link for the ICTP is




  • String field theory;
  • Pure spinors;
  • Amplitudes;
  • Holography.
