Separating Matchings in Cubic Graphs

Juan Gutiérrez, Renzo Gómez

We study separating matchings in graphs, that is, matchings whose removal increases the number of connected components, and focus on determining the maximum size of such a matching…

PANC: Prior-Aware Normalized Cut via Anchor-Augmented Token Graphs

Juan Gutiérrez, Victor Gutiérrez-García, José Luis Blanco-Murillo

Unsupervised segmentation from self-supervised ViT patches holds promise but lacks robustness: multi-object scenes confound saliency cues, and low-semantic images weaken patch rele…

An Evaluation of Hybrid Annotation Workflows on High-Ambiguity Spatiotemporal Video Footage

Juan Gutiérrez, Victor Gutiérrez, Ángel Mora +2

Manual annotation remains the gold standard for high-quality, dense temporal video datasets, yet it is inherently time-consuming. Vision-language models can aid human annotators an…

The Minimum Subgraph Complementation Problem

Juan Gutiérrez, Sagartanu Pal

Subgraph complementation is an operation that toggles all adjacencies inside a selected vertex set. Given a graph \(G\) and a target class \(\mathcal{C}\), the Minimum Subgraph Com…

Strong-lensing rates of massive black hole binaries in LISA

Juan Gutiérrez, Macarena Lagos

Similarly to electromagnetic (EM) signals, gravitational lensing by intervening galaxies can also affect gravitational waves (GWs). In this paper, we estimate the strong-lensing ra…

Homological epimorphisms in functor categories and singularity categories

Juan Andrés Orozco Gutiérrez, Valente Santiago Vargas

Given a homological epimorphism between -categories, we show that if the ideal satisfies certain conditions…
