We describe the topological behavior of the conjugacy action of the mapping class group of an orientable infinite‐type surface Σ$\Sigma$ on itself by proving that: (1)all conjugacy classes of Map(Σ)$\operatorname{Map}(\Sigma )$ are meager for every Σ$\Sigma$ , (2) Map(Σ)$\operatorname{Map}(\Sigma )$ has a somewhere dense conjugacy class if and only if Σ$\Sigma$ has at most two maximal ends and no non‐displaceable finite‐type subsurfaces, (3) Map(Σ)$\operatorname{Map}(\Sigma )$ has a dense… 

Mapping class groups with the Rokhlin property

We classify the connected orientable 2-manifolds whose mapping class groups have a dense conjugacy class. We also show that the mapping class group of a connected orientable 2-manifold has a comeager



Algebraic and topological properties of big mapping class groups

Let $S$ be an orientable, connected surface with infinitely-generated fundamental group. The main theorem states that if the genus of $S$ is finite and at least 4, then the isomorphism type of the

A primer on mapping class groups

Given a compact connected orientable surface S there are two fundamental objects attached: a group and a space. The group is the mapping class group of S, denoted by Mod(S). This group is defined by

Turbulence, amalgamation, and generic automorphisms of homogeneous structures

We study topological properties of conjugacy classes in Polish groups, with emphasis on automorphism groups of homogeneous countable structures. We first consider the existence of dense conjugacy

Large scale geometry of big mapping class groups

We study the large-scale geometry of mapping class groups of surfaces of infinite type, using the framework of Rosendal for coarse geometry of non locally compact groups. We give a complete

Isomorphisms between curve graphs of infinite-type surfaces are geometric

Let $\phi:\mathcal{C}(S)\to\mathcal{C}(S')$ be a simplicial isomorphism between the curve graphs of two infinite-type surfaces. In this paper we show that in this situation $S$ and $S'$ are

The First Integral Cohomology of Pure Mapping Class Groups

It is a classical result of Powell that pure mapping class groups of connected, orientable surfaces of finite type and genus at least three are perfect. In stark contrast, we construct nontrivial

Automatic continuity for homeomorphism groups of noncompact manifolds

We extend the proof of automatic continuity for homeomorphism groups of manifolds to non-compact manifolds and manifolds with marked points and their mapping class groups. Specifically, we show that,

The end point compactification of manifolds.

Introduction^ This paper originated in trying to show that the one point compactification of an orientable generalized ^-manifold (n-grn) with cohomology isomorphic to Euclidean n-space was an
