Exhaustion of via rigid expansions
Jesús Hernández Hernández, Cristhian E. Hidber
Let be a connected closed non-orientable surface of genus at least 6. In this work we prove that there exists a finite subgraph (Irmak's finite rigid set from ``…

First integral cohomology group of the pure mapping class group of a non-orientable surface of infinite type
Jesús Hernández Hernández, Cristhian E. Hidber
In this work we compute the first integral cohomology of the pure mapping class group of a non-orientable surface of infinite topological type and genus at least 3. To this purpose…

On the dimension of the mapping class groups of a non-orientable surface
Cristhian E. Hidber, Luis Jorge Sánchez Saldaña, Alejandra Trujillo-Negrete
Let be the mapping class group of a non-orientable closed surface. We prove that the proper cohomological dimension, the proper geometric dimension, and the virtual…
