Generalized Fuzzy Torus and its Modular Properties
Symmetry, Integrability and Geometry: Methods and Applications, 2013 We consider a generalization of the basic fuzzy torus to a fuzzy torus with non-trivial modular parameter, based on a finite matrix algebra. We discuss the modular properties of this fuzzy torus, and compute the matrix Laplacian for a scalar field.

Synthesis of wild orchid trade and demography provides new insight on conservation strategies
Conservation Letters, 2020 Illegal wildlife trade represents a global conservation priority, but the booming illegal trade in wild plants remains understudied. We use the Mexican orchid trade to illustrate an interdisciplinary approach to provide novel insight on conservation ...

Environmental Research Letters, 2018 The ability to harmonize data sources with varying temporal, spatial, and ecosystem measurements (e.g. forest structure to soil organic carbon) for creation of terrestrial carbon baselines is paramount to refining the monitoring of terrestrial carbon ...

On Products of Random Matrices
Entropy, 2020 We introduce a family of models, which we name matrix models associated with children’s drawings—the so-called dessin d’enfant. Dessins d’enfant are graphs of a special kind drawn on a closed connected orientable surface (in the sky).

The formal demography of kinship VI: Demographic stochasticity and variance in the kinship network [PDF]
Demographic ResearchBACKGROUND: Although the matrix model for kinship networks includes many demographic processes, it is deterministic. It provides values of age-stage distributions of kin, but no information on (co)variances. Because kin populations are small, demographic

An Index for Intersecting Branes in Matrix Models
Symmetry, Integrability and Geometry: Methods and Applications, 2013 We introduce an index indicating the occurrence of chiral fermions at the intersection of branes in matrix models. This allows to discuss the stability of chiral fermions under perturbations of the branes.

Matrix Models for Eigenstate Thermalization
Physical Review X, 2023 We develop a class of matrix models that implement and formalize the eigenstate thermalization hypothesis (ETH) and point out that, in general, these models must contain non-Gaussian corrections in order to correctly capture thermal mean-field theory or ...

Second moment fuzzy-field-theory-like matrix models
Journal of High Energy Physics, 2020 We solve a multitrace matrix model approximating the real quartic scalar field theory on the fuzzy sphere and obtain its phase diagram. We generalize this method to models with modified kinetic terms and demonstrate its use by investigating models ...

Probabilistic projections of distributions of kin over the life course [PDF]
Demographic ResearchBACKGROUND: Mathematical kinship demography is an expanding area of research. Recent papers have explored the expected number of kin a typical individual should experience.

The Multitrace Matrix Model of Scalar Field Theory on Fuzzy CP^n
Symmetry, Integrability and Geometry: Methods and Applications, 2010 We perform a high-temperature expansion of scalar quantum field theory on fuzzy CP^n to third order in the inverse temperature. Using group theoretical methods, we rewrite the result as a multitrace matrix model.
