I will review the efforts for completion of $R^4$ couplings in type II theories. Notably I'll present some higher-point nonlinear NS sector results, duality tests and implications for IIB SL(2)-invariant action.

Bio：Ruben Minasian works on the geometrical aspects of string theory and quantum gravity. He has made contributions to the study of string dualities, anomaly cancellation mechanism in M-theory and string theory, and flux compactifications. Notably, with G. Moore he made the first proposal that D-brane charges are classified by K-theory of spacetime. Based on anomaly cancellation he has proposed new eleven-dimensional couplings that have been fundamental to our current understanding of M-theory, and studied extensively quantum corrections in effective theories. He has been among the pioneers of generalized complex geometry and its applications to string compactifications.
