Time-Varying Data as Sheaves: an Invitation to Narratives
Wilmer Leal, Benjamin Merlin Bumpus, Jana K. Nickel +3
Modern science and engineering increasingly rely on time-varying data, yet the mathematical tools used to model temporal phenomena are often developed within separate disciplines,…
Decomposing time-varying data into simple pieces: structured decompositions of narratives
Benjamin Merlin Bumpus, Jana K. Nickel
Graphs that change over time arise throughout applications, but there is no single standard way to decompose them into smaller pieces. In this paper, we propose a systematic catego…
: Truly Linear FPT
Benjamin Merlin Bumpus, Rod Downey, Tala Eagling-Vose +7
Parameterized complexity has always been concerned with practical computing: by confining combinatorial explosion to a secondary parameter , one can uncover why and how many NP-…
A Parameterized Algorithm for Testing whether the Limit of a Diagram is Empty
Ernst Althaus, Benjamin Merlin Bumpus, James Fairbanks +2
A limit of a (small) diagram in a complete category can be thought of as specifying a set of equations involving the objects of . To motivate this intuitively,…
