Non-archimedean integrals as limits of complex integrals [PDF]
, 2020 We explain how non-archimedean integrals considered by Chambert-Loir and Ducros naturally arise in asymptotics of families of complex integrals. To perform this analysis we work over a non-standard model of the field of complex numbers, which is endowed ...

E-T-lipschitzian and E-T-kernel aggregation operators
, 2007 Lipschitzian and kernel aggregation operators with respect to natural T-indistinguishability operators ET and their powers are studied. A t-norm T is proved to be ET-lipschitzian, and is interpreted as a fuzzy point and a fuzzy map as well.

Properties of Hierarchical Archimedean Copulas [PDF]
In this paper we analyse the properties of hierarchical Archimedean copulas. This class is a generalisation of the Archimedean copulas and allows for general non-exchangeable dependency structures. We show that the structure of the copula can be uniquely

On the stability of orthogonal bases in non-archimedean metrizable locally convex spaces [PDF]
, 2001 It is proved that an orthogonal basis in a non-archimedean metrizable locally convex space E (in particular, a Schauder basis in a non-archimedean Frechet space E) is stable if and only if there is a continuous norm on E.

On Spaces of Compact Operators in Non-Archimedean Banach Spaces
, 1989 Let K be a non-trivial complete non-Archimedean valued field and let E be an infinite-dimensional Banach space over K. Some of the main results are:(1) K is spherically complete if and only if every weakly convergent sequence in l∞ is norm-convergent.(2)

T-norms with strong negations: Solution of two open problems
, 2018 Two open problems of Jayaram are solved. Firstly, we prove that an Archimedean triangular norm with a strong associated negation is necessarily left-continuous.

Norm-closed intervals of norm-complete ordered abelian groups
, 1997 International audienceLet $(G,u)$ be an archimedean norm-complete dimension group with order unit. Continuing a previous paper, we study intervals (i.e., nonempty upward directed lower subsets) of $G$ which are closed with respect to the canonical norm ...

Nested Archimedean Copulas Meet R: The nacopula Package [PDF]
The package nacopula provides procedures for constructing nested Archimedean copulas in any dimensions and with any kind of nesting structure, generating vectors of random variates from the constructed objects, computing function values and probabilities

Distributive lattices of t-k-Archimedean semirings [PDF]
, 2011 A semiring S in ⁺ is a t-k-Archimedean semiring if for all a,b ∈ S, b ∈ √(Sa) ∩ √(aS). Here we introduce the t-k-Archimedean semirings and characterize the semirings which are distributive lattice (chain) of t-k-Archimedean semirings.

A note on logical connectives with weak duality [PDF]
, 2015 The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-16235-5_2We study the weak duality S(x, N(x)) = N(T (x, N(x))) where S is a continuous t-conorm, T is a continuous t-norm and N is a strong negation.
