“…Here, D a is the annular diagram consisting of two parallel b, c arcs and an a arc that differs by a positive Dehn twist. The result is also true if we replace D a with either of D b or D c , or their mirrors (Remark 5.6 [GM18]). Here and in the sequel, we draw a grey arc to indicate arbitrary curves or arcs as in [GM18].…”

“…Its mirror image gives a diagram for ν(P + ). Gay and Meier [GM18] studied the special case of surgery along 2-knots in detail. To perform a Gluck twist, no boundary stabilization is needed, and for our purposes the relevant result is the following (Theorem C Part 2):…”

“…Trisections of 4-manifolds were introduced by Gay and Kirby in 2012 as a 4dimensional analogue of Heegaard splittings. Recently, they have been used to prove classical results [LC18] [LC19], as well as understand embedded surfaces via bridge trisection diagrams [MZ18] [GM18]. We extend these ideas, using trisections to understand certain surgeries on 4-manifolds.…”
A theorem of Katanaga, Saeki, Teragaito, and Yamada shows that the Price twist generalizes the Gluck twist of a 4-manifold. We are able to give a new proof of this theorem using certain trisection diagrams and recent techniques of Gay and Meier, and Kim and Miller. In particular, this answers a question of Kim and Miller.

“…A new tool in smooth four-manifold topology has recently been introduced under the name of trisected Morse 2-functions (or trisections for short) by Gay and Kirby [GK16]. Recent developments in this area demonstrate rich connections and applications to other aspects of four-manifold topology, including a new approach to studying symplectic manifolds and their embedded submanifolds [LMS20; Lam19; LM18], and to surface knots (embedded in S 4 and other more general 4-manifolds) [MZ17; MZ18] along with associated surgery operations [GM18;KM20].…”
Given a smooth, compact four-manifold X viewed as a cobordism from the empty set to its connected boundary, we demonstrate how to use the data of a trisection map π : X 4 → R 2 to compute the induced cobordism maps on Heegaard Floer homology associated to X.

In this note we provide a generalization for the definition of a trisection of a 4-manifold with boundary. We demonstrate the utility of this more general definition by finding a trisection diagram for the Cacime Surface, and also by finding a trisection-theoretic way to perform logarithmic surgery. In addition, we describe how to perform 1-surgery on closed trisections. The insight gained from this description leads us to a classification of the Farey trisection diagrams.
