Michał Baczyński (auth.), Humberto Bustince, Javier's Aggregation Functions in Theory and in Practise: Proceedings PDF

By Michał Baczyński (auth.), Humberto Bustince, Javier Fernandez, Radko Mesiar, Tomasas Calvo (eds.)

This quantity collects the prolonged abstracts of forty five contributions of members to the 7th overseas summer season tuition on Aggregation Operators (AGOP 2013), held at Pamplona in July, 16-20, 2013. those contributions hide a really huge diversity, from the only theoretical ones to these with a extra utilized concentration. additionally, the summaries of the plenary talks and tutorials given on the similar workshop are included.

Together they supply an exceptional review of modern developments in learn in aggregation features which are of curiosity to either researchers in Physics or arithmetic engaged on the theoretical foundation of aggregation services, and to engineers who require them for applications.

Frechet areas were studied because the days of Banach. those areas, their inductive limits and their duals performed a renowned function within the improvement of the idea of in the community convex areas. they are also typical instruments in lots of parts of actual and intricate research. The pioneering paintings of Grothendieck within the fifties has been one of many very important assets of thought for examine within the conception of Frechet areas.

The function Cu,f ,gδ defined by (3) is called an upper semiquadratic function with diagonal section δ . 2 Horizontal and Vertical Semiquadratic Copulas with a Given Diagonal Section Horizontal (resp.

For example, the copula Kδ , defined by Kδ (x, y) = min(x, y, (δ (x) + δ (y))/2), is the greatest symmetric copula with a given diagonal section δ [11] (see also [5, 7]). Moreover, the Bertino copula Bδ defined by Bδ (x, y) = min(x, y) − min{t − δ (t) | t ∈ [min(x, y), max(x, y)]} , is the smallest copula with a given diagonal section δ . Note that Bδ is symmetric. Similarly, the opposite diagonal section of a copula C is the function ωC : [0, 1] → [0, 1] defined by ωC (x) = C(x, 1 − x). e. for all x, x ∈ [0, 1], it holds that ω (x ) − ω (x) ≤ x − x .
