Fourier quasicrystals with unit masses.
(Peer reviewed; Journal article, 2020)The sum of δ-measures sitting at the points of a discrete set Λ⊂R forms a Fourier quasicrystal if and only if Λ is the zero set of an exponential polynomial with imaginary frequencies. -
Functorially finite hearts, simple-minded systems in negative cluster categories, and noncrossing partitions
(Peer reviewed; Journal article, 2022)Let Q be an acyclic quiver and w 1 be an integer. Let C−w(kQ) be the (−w)-cluster category of kQ. We show that there is a bijection between simple-minded collections in Db(kQ) lying in a fundamental domain of C−w(kQ) and ... -
Interpolation of weighted extremal functions
(Peer reviewed; Journal article, 2021-03)An approach to interpolation of compact subsets of Cn, including Brunn–Minkowski type inequalities for the capacities of the interpolating sets, was developed in [8] by means of plurisubharmonic geodesics between relative ... -
Learning the nonlinear flux function of a hidden scalar conservation law from data
(Peer reviewed; Journal article, 2023-10)Nonlinear conservation laws are widely used in fluid mechanics, biology, physics, and chemical engineering. However, deriving such nonlinear conservation laws is a significant and challenging problem. A possible attractive ... -
Mathematical Analysis of Two Competing Cancer Cell Migration Mechanisms Driven by Interstitial Fluid Flow
(Peer reviewed; Journal article, 2020-04)Recent experimental work has revealed that interstitial fluid flow can mobilize two types of tumor cell migration mechanisms. One is a chemotactic-driven mechanism where chemokine (chemical component) bounded to the ...
