Quantitative Syntactic Stylistics of Contemporary Written Czech
(Kvantitatívna syntaktická štylistika súčasnej písanej češtiny)
Anotácia (EN):
In the lecture, the preliminary results of the research project Quantitative Syntactic Stylistics of Contemporary Written Czech will be presented. The research is based on the quantitative analysis of the corpus SYN2020 which is a syntactically annotated, representative corpus of contemporary written Czech. The corpus consists of 100 million tokens. Various syntactic features such as mean sentence length, sentence types, word order, modality, distribution of syntactic functions, indicators of attributivity and subjectivity are analyzed.

The methods of age calculation of very young asteroid families

Abstrakt:
Asteroid families are groups of minor planets that have a common origin in a catastrophic breakup event. Very young compact asteroid clusters are a natural laboratory in which to study the impact processes and dynamics of asteroid orbits. We define the term very young asteroid families (VYFs), that is to say, younger than 1.6 Myrs. We present two different methods age calculation of VYFs. First method employed to calculate the components of relative velocity using the results of backward numerical integration as a method of studying VYFs. We now apply the Fourier approximation to studying the perturbations of Ceres and Vesta on VYFs in the second method. We showed that the approximation using the Fourier series gives a very satisfactory approximation of the evolution of the orbital elements (eccentricity and inclinations). As a result, we obtain the reduced range of ages of some VYFs and the quantitative estimation of Ceres and Vesta effects on members of VYFs.

Prednáška:
All measurements in a probabilistic theory are compatible if and only if
the state space is a simplex

Abstrakt:
It is long-known that classical systems are characterized by a state space that is a simplex and that for classical systems all measurements are compatible. We will introduce General probabilistic theories (GPT) as the general apparatus describing measurements in both classical and quantum mechanics and we will define the compatibility of measurements in GPT. Restricting ourselves to finite-dimensional state spaces we will formulate the proposition that incompatible measurements in any GPT exist whenever the system is not classical and we will demonstrate several key aspects of the proof of the proposition as well as give further insight on the interpretation of the result, based on some future work.

Prednáška:
Decoherent markovian evolutions on non-commutative algebras

Abstrakt:
We consider markovian evolutions on (generally non-commutative) von Neumann algebras. The decoherence-free algebra can be seen as a subalgebra of the domain on which the evolution is a *-homomorphism. The interest in studying the decoherence-free algebra stays in its strict relations with many asymptotic and probabilistic properties of the evolution: ergodicity, environmental decoherence, period,... We shall explore these aspects and some main results. We have studied in particular decoherence induced by the environment (as introduced by Blanchard and Olkiewicz, Rev. Math. Phys., 2003) for quantum Markov semigroups. We have proved sufficient and/or necessary conditions for decoherence and we have studied the link with different types of decompositions of the domain.

Prednáška:
Duality: random variables and observables

Abstrakt:
In generalized probability we encounter three basic maps; probability measures, random variables and observables. While probability measures can be considered as a special case of observables, the relationship between random variables and observables can be described in terms of a categorical duality.

Prednáška:
Factorizing observables

Abstrakt:
Categorical approach to probability leads to better understanding of basic notions and constructions in generalized (fuzzy, operational, quantum) probability, where observables - dual notions to generalized random variables (statistical maps) - play a major role. Our goal is to show that two constructions involving observables: representation of generalized random variables via products, resp. smearing of sharp observables, can be described as factorizing a morphism into composition of two morphisms having desired properties.

Prednáška: Compatibility properties of extreme quantum observables

Abstract: Recently a problem concerning the equivalence of joint measurability and coexistence of quantum observables was solved [D. Reeb, D. Reitzner, and M. M. Wolf, J. Phys. A: Math. Theor. vol 46, 462002 (2013)]. We generalize two known joint measurability results from sharp observables to the class of extreme observables and study relationships between coexistence, joint measurability, and post-processing of quantum observables when an extreme observable is involved. We also discuss another notion of compatibility and provide a counterexample separating this from the former notions.
