| Aug 16, 2011 at 8:51 | comment | added | Nicola Ciccoli | Just to add a small comment on the categorical side: what happens here is quite common. A group object in the category of groups, for example, is an abelian group. This is exactly due to the fact that inversion is an antihomomorphism. I wonder whether there is a notion of category+involutive functor in which a "group-like" object can be defined clarifying the situation. | |

| Aug 15, 2011 at 15:43 | comment | added | Todd Trimble | "I read somewhere on MO that the correct definition of a morphism between Poisson manifolds is a Lagrangian submanifold of their product." Does this have something to do with coisotropic calculus? | |
