DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PUHET/10/">S
 olving unitarity with contraction mappings</a>\nby Alexander Zhiboedov (CE
 RN) as part of Princeton HET seminar\n\n\nAbstract\nI will discuss the pro
 blem of constructing relativistic\, unitary and crossing-symmetric\nscatte
 ring amplitudes in higher-dimensional gapped theories. I will review the i
 mplications of \nelastic unitarity and crossing\, as well as the observati
 on that the resulting structure can be nonperturbatively realized\nusing t
 he contraction mapping theorem. I will report on the numerical implementat
 ion of the idea of solving unitarity\nwith contraction mappings in a simpl
 ified context of 2d S-matrices.\n
