WebCohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

WebA torsor, or more precisely a -torsor, is a sheaf of sets on endowed with an action such that whenever is nonempty the action is simply transitive, and for every the stalk is nonempty. A morphism of -torsors is simply a morphism of sheaves of sets compatible with the -actions. The trivial -torsor is the sheaf endowed with the obvious left -action. WebNov 17, 2024 · 2.
