We study trisections of smooth, compact non-orientable 4-manifolds, and introduce trisections of non-orientable 4-manifolds with boundary. In particular, we prove a non-orientable analogue of a classical theorem of Laudenbach-Poenaru. As a consequence, trisection diagrams and Kirby diagrams of closed non-orientable 4-manifolds exist. We discuss how the theory of trisections may be adapted to the setting of non-orientable 4-manifolds with many examples. 

An algorithm taking Kirby diagrams to trisection diagrams

An algorithm taking a Kirby diagram of a closed oriented 4 -manifold to a trisection diagram of the same manifold is presented and extended to work for the non-orientable case.

Lefschetz fibrations on nonorientable 4-manifolds

Let $W$ be a nonorientable $4$-dimensional handlebody without $3$- and $4$-handles. We show that $W$ admits a Lefschetz fibration over the $2$-disk, whose regular fiber is a nonorientable surface

The relative $\mathcal{L}$-invariant of a compact $4$-manifold.

In this paper, we introduce the relative $\mathcal{L}$-invariant $r\mathcal{L}(X)$ of a smooth, orientable, compact 4-manifold $X$ with boundary. This invariant is defined by measuring the lengths of

Nonorientable 4-manifolds with fundamental group of order 2

In this paper we classify nonorientable topological closed 4-manifolds with fundamental group Z/2 up to homeomorphism. Our results give a complete list of such manifolds, and show how they can be

Diagrams for Relative Trisections

We establish a correspondence between trisections of smooth, compact, oriented $4$--manifolds with connected boundary and diagrams describing these trisected $4$--manifolds. Such a diagram comes in

Trisecting 4–manifolds

We show that any smooth, closed, oriented, connected 4‐manifold can be trisected into three copies of \ k .S 1 B 3 /, intersecting pairwise in 3‐dimensional handlebodies, with triple intersection a

Homotopy invariants of nonorientable 4-manifolds

We define a Z 4 -quadratic function on π 2 for nonorientable 4-manifolds and show that it is a homotopy invariant. We then use it to distinguish homotopy types of certain manifolds that arose from an

Trisections and spun four-manifolds

We study trisections of 4–manifolds obtained by spinning and twistspinning 3–manifolds, and we show that, given a (suitable) Heegaard diagram for the 3–manifold, one can perform simple local

Relative trisections of smooth 4-manifolds with boundary

We show that every smooth, compact, connected, oriented 4–manifold with non-empty (connected or disconnected) boundary can be decomposed into three diffeomorphic 4–dimensional 1–handlebodies, \S × B,

Multisections of piecewise linear manifolds

Recently Gay and Kirby described a new decomposition of smooth closed $4$-manifolds called a trisection. This paper generalises Heegaard splittings of $3$-manifolds and trisections of $4$-manifolds

Classification of trisections and the Generalized Property R Conjecture

We show that the members of a large class of unbalanced four-manifold trisections are standard, and we present a family of trisections that is likely to include non-standard trisections of the

Trisections of 4-manifolds with boundary

This work shows how to turn a certain standard decomposition of a 4-manifold with boundary into a diagram drawn on a surface that describes that 4- manifold and its trisection given certain boundary conditions, and makes the original proof of the existence of relative trisections more explicit in terms of handles.

Isotopies of surfaces in 4–manifolds via banded unlink diagrams

In this paper, we study surfaces embedded in $4$-manifolds. We give a complete set of moves relating banded unlink diagrams of isotopic surfaces in an arbitrary $4$-manifold. This extends work of
