-dimensional Observables on -Perfect MV-Algebras and -Perfect Effect Algebras. II. One-to-one Correspondence
Anatolij Dvurečenskij, Dominik Lachman
The paper is a continuation of the research on a one-to-one correspondence between -dimensional spectral resolutions and -dimensional observables on lexicographic types of qu…
-dimensional Observables on -Perfect MV-Algebras and -Perfect Effect Algebras. I. Characteristic Points
Anatolij Dvurečenskij, Dominik Lachman
In the paper, we investigate a one-to-one correspondence between -dimensional observables and -dimensional spectral resolutions with values in a kind of a lexicographic form…
Lifting, -Dimensional Spectral Resolutions, and -Dimensional Observables
Anatolij Dvurečenskij, Dominik Lachman
We show that under some natural conditions, we are able to lift an -dimensional spectral resolution from one monotone -complete unital po-group into another one, when the fir…
Distance formulas in Bruhat-Tits building of
Dominik Lachman
We study the distance on the Bruhat-Tits building of the group (and its other combinatorial properties). Coding its vertices by certain matrix represe…
Universal Quadratic Forms and Indecomposables over Biquadratic Fields
Martin Čech, Dominik Lachman, Josef Svoboda +2
The aim of this article is to study (additively) indecomposable algebraic integers of biquadratic number fields and universal totally positive quadratic forms wi…
