An Example of Π30-complete Infinitary Rational Relation [PDF]
Computer Science Journal of Moldova, 2007 We give in this paper an example of infinitary rational relation, accepted by a 2-tape Buchi automaton, which is Π30-complete in the Borel hierarchy. Moreover the example of infinitary rational relation given in this paper has a very simple structure and

Philosophy and Phenomenological Research, EarlyView.ABSTRACT I discuss conditions under which maximizing a proxy utility function is harmful and suggest this poses problems for applying decision theory.

Borel liftings of graph limits
, 2016 The cut pseudo-metric on the space of graph limits induces an equivalence relation. The quotient space obtained by collapsing each equivalence class to a point is a metric space with appealing analytic properties.

Repelled Point Processes With Application to Numerical Integration
Scandinavian Journal of Statistics, EarlyView.ABSTRACT We look at Monte Carlo numerical integration from a stochastic geometry point of view. While crude Monte Carlo estimators relate to linear statistics of a homogeneous Poisson point process (PPP), linear statistics of more regularly spread point processes can yield unbiased estimators with faster‐decaying variance, and thus lower integration ...

An Approach of Randomness of a Sample Based on Its Weak Ergodic Limit
Journal of Probability and Statistics, 2017 For a Polish Sample Space with a Borel σ-field with a surjective measurable transformation, we define an equivalence relation on sample points according to their ergodic limiting averages.

Sparse Minimum Redundancy Maximum Relevance for Feature Selection
Scandinavian Journal of Statistics, EarlyView.ABSTRACT We propose a feature screening method that integrates both feature–feature and feature–target relationships. Inactive features are identified via a penalized minimum Redundancy Maximum Relevance (mRMR) procedure, which is the continuous version of the classical mRMR penalized by a non‐convex regularizer, and where the parameters estimated as ...

There Is More Than Meets the Eye: The Dual Role of Perception in Shaping Color Lexicons
Topics in Cognitive Science, EarlyView.Abstract Color's ultimate physical reality is continuous, and yet human beings “cut” this continuum into a rather small number of categories reflected in their languages’ color lexicon. There are striking cross‐linguistic differences in the color lexicon, which are primarily attributed to differences in communicative needs, but also striking ...

Borel complexity of the set of typical numbers [PDF]
In the present note we study the interrelations between the sets of so-called typical numbers and numbers that are normal in base two. Employing results by Nakai and Shiokawa, we exhibit examples of numbers that belong to one set but do not belong to the

On the set of orbits for a Borel subgroup
Commentarii Mathematici Helvetici, 1995 Let \(X = G/H\) be a homogeneous variety for a connected complex reductive group \(G\) and let \(B\) be a Borel subgroup of \(G\). In many situations, it is necessary to study the \(B\)-orbits in \(X\). An equivalent setting of this problem is to analyze \(H\)-orbits in the flag variety \(G/B\).

Frequency‐dependent contraction rates for the Bayesian method to the inverse source problem
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract This paper addresses an inverse source problem for acoustic waves in a range of frequencies. Our study has two main goals. First, although the problem is severely ill‐posed with a logarithmic stability estimate, we demonstrate, through careful analysis of the forward map's singular values, that increasing the frequency range enhances stability,
