Families of Sets in Constructive Measure Theory [PDF]
We present the first steps of a predicative reconstruction of the constructive Bishop-Cheng measure theory. Working in a semi-formal elaboration of Bishop's set theory and invoking the notion of a set-indexed family of subsets (of a given set), we arrive at notions of a pre-integration space and of a pre-measure space.

Multi-fuzzy Rough Sets based on Implicators and Continuous t-norms
This paper extends the study of multi-fuzzy rough sets using an implicator and a continuous t-norm and thus introduces multi-fuzzy rough sets based on fuzzy logical connectives.

Introduction: Walking through the streets of the historic center of Naples and taking a glance at the sky, you may notice that its skyline is determined by the countless peculiar architectural elements, the domes precisely, that stand out from the ...

La hipótesis generalizada del continuo (HGC) y su relación con el axioma de elección (AE)
The so called Generalized Continuum Hypothesis (GCH) is the sentence: "If A is an infinile set whose cardinal number is K and 2K denotes the cardinal number of the set P(A) of subsets of A (the power set of A), and K + denotes the succesor cardinal of K,

Recursive models for constructive set theories
AbstractWe define recursive models of Martin-Löf's (type or) set theories. These models are a sort of recursive realizability; in fact, we show that for implication-free formulae of HAω, satisfaction in the model coincides with mr-HEO realizability. Using an idea of Aczel, we extend the model to a recursive model of the constructive set theories of ...

Rudimentary and arithmetical constructive set theory
Abstract The aim of this paper is to formulate and study two weak axiom systems for the conceptual framework of constructive set theory (CST). Arithmetical CST is just strong enough to represent the class of von Neumann natural numbers and its arithmetic so as to interpret Heyting Arithmetic.

A set-theoretic approach to linguistic feature structures and unification algorithms (I) [PDF]
The paper proposes formal inductive definitions for linguistic feature structures (FSs) taking values within a class of value types or sorts: single, disjunctive, (ordered) lists, multisets (or bags), po-multisets (multisets embedded into a partially ...

The digits of the Pierce expansion satisfy the law of large numbers. It is known that the Hausdorff dimension of the set of exceptions to the law of large numbers is $ 1 $.
