Titre  Tensionless Strings at OneLoop 
Résumé  It is expected that the AdS/CFT correspondence may be used to define a theory of tensionless strings in AdS space by setting the 'tHooft coupling of the dual CFT to zero. Higherspin/CFT dualities are heuristically a truncated version of this window of stringy AdS/CFT. We review oneloop tests of the Higherspin/CFT dualities and describe extensions of such computations to various more `stringy' theories such as the bulk dual of free SU(N) YangMills, and finally type IIB strings in AdS(5) x S(5). We also describe new techniques which make such computations possible. These computations are independent of supersymmetry, though we observe interesting simplifications which occur only for maximal supersymmetry. This is somewhat in contrast to the usual situation in higherspin theories where supersymmetry does not lead to any obvious simplifications. The talk will be based on work in collaboration with Jinbeom Bae and Euihun Joung (chiefly arXiv:1603.05387 arXiv:1607.07651, and arXiv:1701.01507).
