From flops to diffeomorphism groups

چکیده
We exhibit many examples of closed complex surfaces whose diffeomorphism groups are not simply-connected and contain loops that homotopic to symplectomorphisms.

Homomorphisms between Diffeomorphism Groups
For r ≥ 3, p ≥ 2, we classify all actions of the groups Diffc(R) and Diff+(S) by Cdiffeomorphisms on the line and on the circle. This is the same as describing all nontrivial group homomorphisms between groups of compactly supported diffeomorphisms on 1-manifolds. We show that all such actions have an elementary form, which we call topologically diagonal. As an application, we answer a question...
متن کاملDiffeomorphism groups of critical regularity
Let M be a circle or a compact interval, and let α “ k ` τ ě 1 be a real number such that k “ tαu. We write Diff`pMq for the group of orientation preserving Ck diffeomorphisms of M whose kth derivatives are Hölder continuous with exponent τ. We prove that there exists a continuum of isomorphism types of finitely generated subgroups G ď Diff`pMq with the property that G admits no injective homom...
متن کاملQuantum and Braided Diffeomorphism Groups
We develop a general theory of ‘quantum’ diffeomorphism groups based on the universal comeasuring quantum group M(A) associated to an algebra A and its various quotients. Explicit formulae are introduced for this construction, as well as dual quasitriangular and braided R-matrix versions. Among the examples, we construct the q-diffeomorphisms of the quantum plane yx = qxy, and recover the quant...
متن کاملFactor Representations of Diffeomorphism Groups
General semifinite factor representations of the diffeomorphism group of euclidean space are constructed by means of a canonical correspondence with the finite factor representations of the inductive limit unitary group. This construction includes the quasi-free representations of the canonical commutation and anti-commutation relations. To establish this correspondence requires a non-linear fo...
متن کاملStable Diffeomorphism Groups of 4-manifolds
A localisation of the category of n-manifolds is introduced by formally inverting the connected sum construction with a chosen nmanifold Y . On the level of automorphism groups, this leads to the stable diffeomorphism groups of n-manifolds. In dimensions 0 and 2, this is connected to the stable homotopy groups of spheres and the stable mapping class groups of Riemann surfaces. In dimension 4 th...
