Abstract
AbstractFor every $$n\ge 2$$
n
≥
2
, the surface Houghton group$${\mathcal {B}}_n$$
B
n
is defined as the asymptotically rigid mapping class group of a surface with exactly n ends, all of them non-planar. The groups $${\mathcal {B}}_n$$
B
n
are analogous to, and in fact contain, the braided Houghton groups. These groups also arise naturally in topology: every monodromy homeomorphism of a fibered component of a depth-1 foliation of closed 3-manifold is conjugate into some $${\mathcal {B}}_n$$
B
n
. As countable mapping class groups of infinite type surfaces, the groups $$\mathcal {B}_n$$
B
n
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 $$\mathcal {B}_n$$
B
n
is of type $$\text {F}_{n-1}$$
F
n
-
1
, but not of type $$\text {FP}_{n}$$
FP
n
, analogous to the braided Houghton groups.
