Mathematical Foundations of Randomness

TL;DR: There are three key approaches for defining randomness in sequences: unpredictability, typicality, and incompressibility as discussed by the authors, which have dominated algorithmic randomness: Von Mises randomness, Martin-Lof randomness and Kolmogorov complexity.

Mind change efficient learning

TL;DR: It is shown that the characteristic property of strongly mind change optimal learners is that they output conjectures (languages) with maximal accumulation order, which is related to other established notions of structural complexity, such as thickness and intrinsic complexity.

The importance of Π⁰₁ classes in effective randomness

TL;DR: A number of results in effective randomness are proved, including the fact that every PA Turing degree is the join of two random Turing degrees, and the existence of a minimal pair of LR degrees below the LR degree of the halting problem.

A semantical proof of De Jongh's theorem

TL;DR: By a refinement of De Jongh's original method, a semantical proof is given of a result that is almost as good as Leivant's, and maximality of intuitionistic predicate calculus is established wrt.

Subspaces of computable vector spaces

TL;DR: In this article, the existence of a nontrivial proper subspace of a vector space of dimension greater than one (over an infinite field) is shown to be equivalent to WKL 0 over RCA 0.
