The authors investigates the free archimedean (abelian) \(\ell\)-group generated by a po-group \([G,P]\) \((P= \{x\in G\): \(x\geq 0\})\). Main results: 1. There exists an archimedean free \(\ell\)-group generated by a po-group \([G,P]\) if and only if \([G,P]\) is a po-group isomorphic to an archimedean \(\ell\)-group. 2.

Some New Bivariate Properties and Characterizations Under Archimedean Copula
This paper considers comparing properties and characterizations of the bivariate functions under Archimedean copula. It is shown that some results of the usual stochastic order for the bivariate functions in the independent case are generalized to the ...

Heights and measures on analytic spaces. A survey of recent results, and some remarks
This paper has two goals. The first is to present the construction, due to the author, of measures on non-archimedean analytic varieties associated to metrized line bundles and some of its applications.

VALUE AT RISK ESTIMATION FOR STOCK PORTFOLIO USING THE ARCHIMEDEAN COPULA APPROACH
Investment is one of the many ways to achieve future profits. One form of investment that is widely made is stocks. The return obtained in investing in stocks is potentially higher than other investment alternatives, but the risks borne are amplified, so

Strict topoligies in non-Archimedean function spaces
Let F be a non-trivial complete non-Archimedean valued field. Some locally F-convex topologies, on the space Cb(X,E) of all bounded continuous functions from a zero-dimensional topological space X to a non-Archimedean locally F-convex space E, are ...

Copulae sind in der multivariaten Statistik und Finanzapplikationen von großer Bedeutung. Eine wichtige Copula-Famlie sind die Archimedischen Copulae. Für parametrische Copulafamilien gibt es bereits eine Fülle an Tests zur Anpassungsgüte. Die Hypothese, dass eine Copula eine beliebige Archimedische Copula ist, wurde dagegen bisher in der Literatur ...

On bivariate Archimedean copulas with fractal support
Due to their simple analytic form (bivariate) Archimedean copulas are usually viewed as very smooth and handy objects, which should distribute mass in a fairly regular and certainly not in a pathological way. Building upon recently established results on

Archimedean operator-theoretic Positivstellensätze
We prove a general archimedean positivstellensatz for hermitian operator-valued polynomials and show that it implies the multivariate Fejer-Riesz Theorem of Dritschel-Rovnyak and positivstellens tze of Ambrozie-Vasilescu and Scherer-Hol. We also obtain several generalizations of these and related results.

A remark on stationary fuzzy metric spaces
The main result states that the category of stationary fuzzymetric spaces (with respect to an archimedean $t$-norm) andnonexpanding maps is isomorphic to a full subcategory of thecategory of metric spaces and nonexpanding maps.
