Cellular Sheaves of Hilbert spaces

Julian Gould

PhD thesis, 2025

My PhD thesis. This work introduces cellular sheaves of Hilbert spaces, a powerful infinite-dimensional generalization of weighted cellular sheaves. Applications include graph neural networks, opinion dynamics, and clock synchronization problems.

Hilbert Sheaf Machine Learning

Claudio Battiloro, Julian Gould, and Kartik Tandon

In preparation, 2025

An application of cellular sheaves of Hilbert spaces to graph neural networks.

Categorical Linear Programming

Shreya Arya, Robert Ghrist, Julian Gould, Miguel Lopez

In preparation, 2025

A new framework for linear programming via enriched category theory and the Chu construction.

Clearing Sections of Lattice Liability Networks

Robert Ghrist, Julian Gould, Miguel Lopez, and Hans Riess

Preprint, 2025

A mathematical framework that unifies and extends the classical Eisenberg-Noe model of financial clearing in terms of networks of lattice-valued liabilities.

Lattice-Valued Bottleneck Duality

Robert Ghrist, Julian Gould, and Miguel Lopez

Preprint, 2025

A qualitative benchmark for the use of large language models in mathematics research. This work reformulates certain classical combinatorial duality theorems in the context of order lattices.

A combinatorial K-theory perspective on the Edge Reconstruction Conjecture in graph theory

Maxine Calle, Julian Gould

Homology, Homotopy and Applications, 2025

A framework for abstract reconstruction problems using the K-theory of categories with covering families, which we then apply to reformulate the edge reconstruction conjecture in graph theory.

Philosophy Papers

Flash War

Kyle Brown, Julian Gould

(In preparation) Chapter in Advancing Ethical and Legal Discussions of AI and Autonomy in Defense Systems

An exploration of the risk of rapid escalation on the battlefield posed by AI decision-making.

Defensive Autonomous Weapon Systems, Humanitarian Intervention, and the Golem of Prague

Julian Gould, Jesse Hamilton

Preprint, 2024

An interdisciplinary paper that explores the ethics of "defensive" autonomous weapons systems through Yudl Rosenberg's rendition of the myth of the Golem of Prague. This paper is currently homeless, and we are looking for a suitable journal.
