The main topics are rotation numbers, the bounded euler class and actions of lattices. In turn, the euler class is the archetype for other characteristic classes of vector bundles, in that each top characteristic class equals the euler class, as follows.

Let us prove by induction that such a sequence exists. In geometry, eulers theorem states that the distance d between the circumcentre and incentre of a triangle is given by.
They are named after the mathematician leonard euler who popularized them in his letters to a german princess 1768. Thus the euler class is a generalization of the euler characteristic to vector bundles other than tangent bundles. Mascheroni mascheroni computed 32 decimal places, but only 19 were correct.
