Topics in orbifold geometry and Gorenstein homogeneous spaces [PDF]

open access: yes
I study two problems from different domains. The first problem is related to orbifold geometry and the second to Gorenstein homogeneous spaces. Though two different topics, they share a common theme: the Gorenstein property.

Bayesian inverse ensemble forecasting for COVID‐19

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...

Competitive Equilibria in Semi-Algebraic Economies [PDF]

open access: yes
This paper examines the equilibrium correspondence in Arrow-Debreu exchange economies with semi-algebraic preferences. We show that a generic semi-algebraic exchange economy gives rise to a square system of polynomial equations with finitely many ...

Large parameter asymptotic analysis for homogeneous normalized random measures with independent increments

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Homogeneous normalized random measures with independent increments represent a broad class of Bayesian nonparametric priors and thus are widely used. In this article, we obtain the strong law of large numbers, the central limit theorem (CLT), and the functional central limit theorem (fCLT) of such measures when the concentration parameter a ...

Algebraic causality : Bayes nets and beyond [PDF]

open access: yes, 2007
The relationship between algebraic geometry and the inferential framework of the Bayesian Networks with hidden variables has now been fruitfully explored and exploited by a number of authors.

Revisiting Fisher's n‐D statistical vision: From algebraic abstraction to modern visualization

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We revisit early foundational results in mathematical statistics derived by Ronald A. Fisher. They involve sampling distributions of statistics calculated from independent and identically distributed Normal observations, namely the root mean square deviation; the mean absolute deviation, conditional on already knowing the value of the root ...

SOME OPEN PROBLEMS IN COMPUTATIONAL ALGEBRAIC GEOMETRY

open access: yesAlbanian Journal of Mathematics, 2007
The development of computational techniques in the last decade has made possible to attack some classical problems of algebraic geometry from a computational viewpoint.

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Exploration of Mathematical Concepts of Numbers, Algebra and Geometry in the Qur'an

open access: yesProceeding of International Conference of Religion, Health, Education, Science and Technology
The Qur'an is a source of knowledge regarding various dimensions of life and the universe created by Allah SWT. The relationship between mathematics and the Koran is very close in everyday life. This research is library research and aims to identify the concepts of Numbers, Algebra and Geometry in the Al-Qur'an.
