Obstructions to combinatorial formulas for plethysm

open access: yes, 2018
Motivated by questions of Mulmuley and Stanley we investigate quasi-polynomials arising in formulas for plethysm. We demonstrate, on the examples of $S^3(S^k)$ and $S^k(S^3)$, that these need not be counting functions of inhomogeneous polytopes of ...

Empowering young minds through STEM education: Engaging high schoolers in Ghana through medical physics

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To promote diversity in Science, Technology, Engineering, and Mathematics (STEM), an educational presentation and hands‐on session was organised to raise awareness of STEM career opportunities among high school girls to introduce the students to the field of medical physics. Materials and Methods The study involved 65 first‐year Senior

Multiplicity one for certain paramodular forms of genus two

open access: yes, 2017
We show that certain paramodular cuspidal automorphic irreducible representations of $\mathrm{GSp}(4,\mathbb{A}_\mathbb{Q})$, which are not CAP, are globally generic.

Comprehensive end‐to‐end dosimetry audit for stereotactic body radiotherapy in spine, lung, and soft tissue

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To create and conduct a comprehensive onsite end‐to‐end dosimetry audit to assess treatment accuracy of spine, lung, and soft tissue Stereotactic Body Radiotherapy (SBRT) across Australian and New Zealand (ANZ) radiotherapy centers. Methods The Australian Clinical Dosimetry Service (ACDS) anthropomorphic thorax phantom underwent a CT ...

Bounds on the Hilbert-Kunz Multiplicity [PDF]

open access: yes, 2011
In this paper we give new lower bounds on the Hilbert-Kunz multiplicity of unmixed non-regular local rings, bounding them uniformly away from one. Our results improve previous work of Aberbach and Enescu.Comment: Some minor typos fixed, especially ...

Commuting Toeplitz Operators on Bounded Symmetric Domains and Multiplicity-Free Restrictions of Holomorphic Discrete Series

open access: yes, 2014
For any given bounded symmetric domain, we prove the existence of commutative $C^*$-algebras generated by Toeplitz operators acting on any weighted Bergman space.

Some Comments on Multiple Discovery in Mathematics

open access: yesJournal of Humanistic Mathematics, 2017
Among perhaps many things common to Kuratowski's Theorem in graph theory, Reidemeister's Theorem in topology, and Cook's Theorem in theoretical computer science is this: all belong to the phenomenon of simultaneous discovery in mathematics. We are interested to know whether this phenomenon, and its close cousin repeated discovery, give rise to ...

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

A multiplicity bound for graded rings and a criterion for the Cohen-Macaulay property [PDF]

open access: yes, 2014
Let $R$ be a polynomial ring over a field. We prove an upper bound for the multiplicity of $R/I$ when $I$ is a homogeneous ideal of the form $I=J+(F)$, where $J$ is a Cohen-Macaulay ideal and $F\notin J$. The bound is given in terms of two invariants of $
