Abstract
For every , the {\em surface Houghton group} is defined as the asymptotically rigid mapping class group of a surface with exactly ends, all of them non-planar. The groups are analogous to, and in fact contain, the braided Houghton groups. These groups also arise naturally in topology: every monodromy homeomorphisms of a fibered component of a depth-1 foliation of closed 3-manifold is conjugate into some . As countable mapping class groups of infinite type surfaces, the groups lie somewhere between classical mapping class groups and big mapping class groups. We initiate the study of surface Houghton groups proving, among other things, that is of type , but not of type , analogous to the braided Houghton groups.
