The computational content of Nonstandard Analysis [PDF]
, 2016 Kohlenbach's proof mining program deals with the extraction of effective information from typically ineffective proofs. Proof mining has its roots in Kreisel's pioneering work on the so-called unwinding of proofs.

A matrix perturbation view of the small world phenomenon [PDF]
, 2003 We use techniques from applied matrix analysis to study small world cutoff in a Markov chain. Our model consists of a periodic random walk plus uniform jumps.

Numerical hyperinterpolation over nonstandard planar regions [PDF]
, 2017 We discuss an algorithm (implemented in Matlab) that computes numerically total-degree bivariate orthogonal polynomials (OPs) given an algebraic cubature formula with positive weights, and constructs the orthogonal projection (hyperinterpolation) of a ...

Notes on nilspaces: algebraic aspects
Discrete Analysis, 2017 Notes on nilspaces: algebraic aspects, Discrete Analysis 2017:15, 59 pp. One of the fundamental insights in modern additive combinatorics is that there is a hierarchy of notions of "pseudorandomness" or "higher order Fourier uniformity" that can be ...

Conversion from nonstandard to standard measure spaces and applications in probability theory [PDF]
Transactions of the American Mathematical Society, 1975 Let ( X , A , ν ) (X,\mathcal {A},\nu ) be an internal measure space in a denumerably comprehensive enlargement. The set X is a standard measure space when equipped with the smallest standard σ \sigma -algebra M \mathfrak {M}

Noncanonical quantization of gravity. II. Constraints and the physical Hilbert space [PDF]
, 2001 The program of quantizing the gravitational field with the help of affine field variables is continued. For completeness, a review of the selection criteria that singles out the affine fields, the alternative treatment of constraints, and the choice of ...

High density piecewise syndeticity of product sets in amenable groups [PDF]
, 2015 M. Beiglb\"ock, V. Bergelson, and A. Fish proved that if $G$ is a countable amenable group and $A$ and $B$ are subsets of $G$ with positive Banach density, then the product set $AB$ is piecewise syndetic.

WZNW Models from Non-Standard Bilinear Forms [PDF]
, 1996 We study the WZNW models based on nonstandard bilinear forms. We approach the problem from algebraic, perturbative and functional exact methods. It is shown that even in the case of integer $k$ we can find irrational CFT's.

S and T Parameters from a Light Nonstandard Higgs versus Near Conformal Dynamics [PDF]
, 2012 We determine the contribution to the $S$ and $T$ parameters coming from extensions of the standard model featuring a light nonstandard-like Higgs particle.
