Solving AdS3 string theory at minimal tension: tree-level correlators
A Dei, B Knighton, K Naderi - Journal of High Energy Physics, 2024 - Springer
A bstract We revisit the minimal tension (k= 1) string theory on AdS 3× S 3× 𝕋 4. We propose
a new free-field description of the worldsheet theory and show how localization of string …

N= 4 topological strings
N Berkovits, C Vafa - Nuclear Physics B, 1995 - Elsevier
We show how to make a topological string theory starting from an N= 4 superconformal
theory. The critical dimension for this theory is c ̂= 2 (c= 6). It is shown that superstrings (in …
