Equal area partitions of the sphere with diameter bounds, via optimal transport
Bulletin of the London Mathematical Society, Volume 57, Issue 5, Page 1524-1538, May 2025.Abstract We prove existence of equal area partitions of the unit sphere via optimal transport methods, accompanied by diameter bounds written in terms of Monge–Kantorovich distances. This can be used to obtain bounds on the expectation of the maximum diameter of partition sets, when points are uniformly sampled from the sphere.

A Shrinkage Instrumental Variable Estimator for Large Datasets [PDF]
This paper proposes and discusses an instrumental variable estimator that can be of particular relevance when many instruments are available. Intuition and recent work (see, e.g., Hahn (2002)) suggest that parsimonious devices used in the construction of

Proving a manifold to be hyperbolic once it has been approximated to be so
, 2008 The computer program SnapPea can approximate whether or not a three manifold whose boundary consists of tori has a complete hyperbolic structure, but it can not prove conclusively that this is so.

Cytometry Part A, Volume 107, Issue 2, Page 126-139, February 2025.ABSTRACT Representing and quantifying Measurable Residual Disease (MRD) in Acute Myeloid Leukemia (AML), a type of cancer that affects the blood and bone marrow, is essential in the prognosis and follow‐up of AML patients. As traditional cytological analysis cannot detect leukemia cells below 5%, the analysis of flow cytometry datasets is expected to ...

Labour Values and the Theory of the Firm: Part I: The Competitive Firm [PDF]
This paper is the first part of a Marxian critique of the theory of the firm, focusing on the analysis of labour values. Starting from Adam Smith's example of the deer hunter marginal analysis is introduced, culminating in the derivation of the Labour ...

A new Kantorovich-type theorem for Newton's method [PDF]
Applicationes Mathematicae, 1999 Summary: A new Kantorovich-type convergence theorem for Newton's method is established for approximating a locally unique solution of an equation \(F(x) =0\) defined on a Banach space. It is assumed that the operator \(F\) is twice Fréchet differentiable, and that \(F'\), \(F''\) satisfy Lipschitz conditions.

A Unifying Local Convergence Result for Newton's Method in Riemannian Manifolds [PDF]
, 2004 We consider the problem of finding a singularity of a vector field $X$ on a complete Riemannian manifold. In this regard we prove a unified result for local convergence of Newton's method.
