Bijective proofs for Schur function identities which imply Dodgson's condensation formula and Pl\"ucker relations

open access: yes, 2000
We present a ``method'' for bijective proofs for determinant identities, which is based on translating determinants to Schur functions by the Jacobi--Trudi identity.

The Mumford conjecture (after Bianchi)

open access: yesJournal of Topology, Volume 18, Issue 1, March 2025.
Abstract We give a self‐contained and streamlined rendition of Andrea Bianchi's recent proof of the Mumford conjecture using moduli spaces of branched covers.

Linking Bipartiteness and Inversion in Algebra via Graph‐Theoretic Methods and Simulink

open access: yesComplexity, Volume 2025, Issue 1, 2025.
Research for decades has concentrated on graphs of algebraic structures, which integrate algebra and combinatorics in an innovative way. The goal of this study is to characterize specific aspects of bipartite and inverse graphs that are associated with specific algebraic structures, such as weak inverse property quasigroups and their isotopes ...

Asymptotics of parity biases for partitions into distinct parts via Nahm sums

open access: yesProceedings of the London Mathematical Society, Volume 129, Issue 6, December 2024.
Abstract For a random partition, one of the most basic questions is: what can one expect about the parts that arise? For example, what is the distribution of the parts of random partitions modulo N$N$? As most partitions contain a 1, and indeed many 1s arise as parts of a random partition, it is natural to expect a skew toward 1(modN)$1\ (\mathrm{mod} \
