DESCRIPTION:Recently\, new positivity constraints were suggested to constr
 ain arbitrary tensor integrals. In this talk\, we explore two variants of 
 these positivity constraints: one built from ``open bubbles''\, which are 
 tensor-like objects found by removing a tensor from a bubble invariant\, a
 nd the second built from ``color matrices''\, which are matrices found by 
 removing a color contraction from a bubble invariant. Using these positivi
 ty constraints\, we find sharp bounds on tensor integrals at finite N\, an
 d explore some features of these integrals.\n\nhttps://indico.math.cnrs.fr
