Decompositions and diagrams of symplectic surfaces in Weinstein domains

Román Aranda, Patricia Cahn, Agniva Roy +1

We introduce combinatorial and diagrammatic methods for representing properly embedded symplectic surfaces in 4-dimensional Weinstein domains. We show that positive ascending surfa…

Bridge position of 3-manifolds embedded in the 5-sphere

Román Aranda, Sarah Blackwell, Geunyoung Kim +2

We introduce and study bridge decompositions for 3-manifolds embedded in the 5-sphere. These generalize both the classical notion of bridge position for knots in the 3-sphere and t…

Trisected Rainbows and Braids

Román Aranda, Scott Carter, Julia Courtney +1

New explicit procedures for passing among triplane diagrams, braid movies, and braid charts for knotted surfaces in are presented. To this end, rainbow diagrams, whi…

Region colorings of surfaces in 4-space

Román Aranda, Noah Crawford, Andrew Maas +6

Niebrzydowski introduced a theory of region colorings for surface links. In this paper, we translate the coloring invariant to the context of triplane diagrams and movies of knots.…

Manifolds with weakly reducible genus-three trisections are standard

Román Aranda, Alexander Zupan

Heegaard splittings stratify 3-manifolds by complexity; only admits a genus-zero splitting, and only , , and lens spaces admit genus-one splitti…

Studying links via booklinks: A Markov theorem

Roman Aranda, Fraser Binns, Margaret Doig

We introduce "book links" as a generalization of braids in open book decompositions; this new class of objects includes both braids and plats as special cases. We then prove a vers…

Bridge Multisections of Knotted Surfaces in

Román Aranda, Carolyn Engelhardt

Bridge multisections are combinatorial descriptions of surface links in 4-space using tuples of trivial tangles. They were introduced by Islambouli, Karimi, Lambert-Cole, and Meier…

Pants distances of knotted surfaces in 4-manifolds

Román Aranda, Sarah Blackwell, Devashi Gulati +4

We define a pants distance for knotted surfaces in 4-manifolds, which generalizes the complexity studied by Blair-Campisi-Taylor-Tomova for surfaces in the 4-sphere. We determine t…

A bound on the number of twice-punctured tori in a knot exterior

Román Aranda, Enrique Ramírez-Losada, Jesús Rodríguez-Viorato

This paper continues a program due to Motegi regarding universal bounds for the number of non-isotopic essential -punctured tori in the complement of a hyperbolic knot in .…

Bounds for Kirby-Thompson invariants of knotted surfaces

Román Aranda, Puttipong Pongtanapaisan, Cindy Zhang

We provide sharp lower bounds for two versions of the Kirby-Thompson invariants for knotted surfaces, one of which was originally defined by Blair, Campisi, Taylor, and Tomova. The…

Bounding the Kirby-Thompson invariant of spun knots

Román Aranda, Puttipong Pongtanapaisan, Scott A. Taylor +1

A bridge trisection of a smooth surface in is a decomposition analogous to a bridge splitting of a link in . The Kirby-Thompson invariant of a bridge trisection measures…

Minimal genus four manifolds

Román Aranda

In 2018, M. Chu and S. Tillmann gave a lower bound for the trisection genus of a closed 4-manifold in terms of the Euler characteristic of and the rank of its fundamental group…

Thin Position through the lens of trisections of 4-manifolds

Román Aranda

Motivated by M. Scharlemann and A. Thompson's definition of thin position of 3-manifolds, we define the width of a handle decomposition a 4-manifold and introduce the notion of thi…

Representativity and waist of cable knots

Román Aranda, Seungwon Kim, Maggy Tomova

We study the incompressible surfaces in the exterior of a cable knot and use this to compute the representativity and waist of most cable knots.
