Let X be a $$(d\times N)$$(d×N)-matrix. We consider the variable polytope $$\varPi _X(u) = \{ w \ge 0 : X w = u \}$$ΠX(u)={w≥0:Xw=u}. It is known that the function $$T_X$$TX that assigns to a
Local stability implies global stability for the 2-dimensional Ricker map
• Mathematics
• 2013
In this study, we consider the difference equation where is a positive parameter and d is a non-negative integer. The case d = 0 was introduced by W.E. Ricker in 1954. For the delayed version of the
Causal Inference Under Unmeasured Confounding With Negative Controls: A Minimax Learning Approach
• Mathematics
ArXiv
• 2021
This paper tackles the primary challenge to causal inference using negative controls: the identification and estimation of these bridge functions, and provides a new identification strategy that avoids both uniqueness and completeness.
Piecewise quadratic bounding functions for finding real roots of polynomials

A new algorithm to obtain roots of the real polynomial represented by f(x) is constructed and it is shown that this algorithm is more useful than others.
The Complex Dynamical Behavior of a Prey-Predator Model with Holling Type-III Functional Response and Non-Linear Predator Harvesting
• Mathematics

ABSTRACT In the present paper we have investigated the impact of predator harvesting in a two-dimensional prey–predator model with Holling type III functional response. The main objective of this
Time-dependent propagators for stochastic models of gene expression: an analytical method
• Mathematics
Journal of mathematical biology
• 2018
An analytical method is proposed for the efficient approximation of propagators of stochastic models for gene expression which lends itself naturally to implementation in a Bayesian parameter inference scheme, and can be generalised systematically to related categories of stoChastic models beyond the ones considered here.
Moving Mesh for the Numerical Solution of Partial Differential Equations
• Computer Science, Mathematics

We derive a general result in microfacet theory: given an arbitrary microsurface defined via standard microfacet statistics, we show how to construct the statistics of its linearly transformed
Nonlinear Laplacian Dynamics: Symmetries, Perturbations, and Consensus
• Mathematics
• 2022
In this paper, we study a class of dynamic networks called Absolute Laplacian Flows under small perturbations. Absolute Laplacian Flows are a type of nonlinear generalisation of classical linear
Wasserstein Distributionally Robust Gaussian Process Regression and Linear Inverse Problems
• Mathematics
• 2022
We study a distributionally robust optimization formulation (i.e., a min-max game) for problems of nonparametric estimation: Gaussian process regression and, more gen-erally, linear inverse problems.
