On Periodic Shadowing Property

In this paper, some properties of the periodic shadowing are presented. It is shown that a homeomorphism has the periodic shadowing property if and only if so does every lift of it to the universal covering space. Also, it is proved that continuous mappings on a compact metric space with the periodic shadowing and the average shadowing property also have the shadowing property and then are chao...

Property-based Semantic Similarity: What Counts?

Similarity, one of six Gestalt principles, is one of the most intuitive ways to perceive the world and categorise the objects surrounding us. The notion of similarity plays an important role in many areas, and it is important to simulate human perception of similarity in order to obtain satisfying results in various applications. We draw our inspiration from Tversky’s work on similarity and def...

What ’ s Intellectual Property Good for ?

1. Introduction Intellectual property may turn out to be among a handful of themes that will accompany us for most of the XXI century, shaping our economic future and maybe not just that. In spite of having been around – with ups and downs – since the times of James Watt, the controversy over intellectual property started anew in the second half of the 1990s and is likely to grow, in both inten...

Combinatorial Property Vs Computational Property

A set C can be strongly coded under condition < B, C(A) >, where B and C are classes of sets possibly with other parameters, iff there exists A ∈ B such that every Z ∈ C(A) can be used to compute C. The issue is widely studied especially in effective mathematics and reverse mathematics. In this paper, we focus on three kinds of conditions, namely, density condition, enumeration condition and pa...
