DESCRIPTION:Bregje Pauwels (Australian National University)\nI will consid
 er separable and Galois extensions of commutative monoids in tensor triang
 ulated categories\, and show how they pop up in various settings.  In sta
 ble homotopy theory\, separable extensions of commutative S-algebras have 
 been studied extensively by Rognes.\nIn modular representation theory\, re
 striction to a subgroup can be thought of as extension along a separable m
 onoid in the (stable or derived) module category. In algebraic geometry\, 
 separable monoids correspond to étale extensions of schemes\, alowing us
  to define a generalized- étale site for any tensor triangulated categor
 y.
