Real Analytic Machines and Degrees [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
We study and compare in two degree-theoretic ways (iterated Halting oracles analogous to Kleene's arithmetical hierarchy and the Borel hierarchy of descriptive set theory) the capabilities and limitations of three models of analytic computation: BSS ...

On the sum of two Borel sets [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
It is shown that the linear sum of two Borel subsets of the real line need not be Borel, even if one of them is compact and the other is \(G_\delta\). This result is extended to a fairly wide class of connected topological groups.

Infinite games with uncertain moves [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
We study infinite two-player games where one of the players is unsure about the set of moves available to the other player. In particular, the set of moves of the other player is a strict superset of what she assumes it to be.

Every Borel function is monotone Borel [PDF]

open access: yes, 1991
Given two internal sets X and Y we prove that every Borel function (in the Descriptive Set Theory of Hyperfinite Sets) whose graph is a subset of the product X x Y is a member of the least set containing the class of all internal functions and closed ...

Borel Directions and Uniqueness of Meromorphic Functions

open access: yesAbstract and Applied Analysis, 2013
We investigate the relationship between Borel directions and uniqueness of meromorphic functions and obtain some results of meromorphic functions sharing four distinct values IM and one set in an angular domain containing a Borel line.

Events of Borel Sets, Construction of Borel Sets and Random Variables for Stochastic Finance [PDF]

open access: yesFormalized Mathematics, 2014
Summary We consider special events of Borel sets with the aim to prove, that the set of the irrational numbers is an event of the Borel sets. The set of the natural numbers, the set of the integer numbers and the set of the rational numbers are countable, so we can use the literature [10] (pp.

Sampling and interpolation of cumulative distribution functions of Cantor sets in [0, 1]

open access: yesDemonstratio Mathematica, 2021
Cantor sets are constructed from iteratively removing sections of intervals. This process yields a cumulative distribution function (CDF), constructed from the invariant Borel probability measure associated with their iterated function systems.

Borel Chromatic Numbers [PDF]

open access: yes, 1999
We study in this paper graph coloring problems in the context of descriptive set theory. We consider graphs G=(X, R), where the vertex set X is a standard Borel space (i.e., a complete separable metrizable space equipped with its σ-algebra of Borel sets),

On the New Description of Exceptional Sets in Asymptotic Estimates for the Entire Functions and the Laplace–Stieltjes Integrals

open access: yesAxioms
We obtain a new extended description of the exceptional set in the asymptotic Borel-type relation in terms of the maximum of the integrand function for the Laplace–Stieltjes integrals.
