We propose results about sign-constancy of Green's functions to impulsive nonlocal boundary value problems in a form of theorems about differential inequalities. One of the ideas of our approach is to construct Green's functions of boundary value problems for simple auxiliary differential equations with impulses. Careful analysis of these Green's functions allows us to get conclusions about the sign-constancy of Green's functions to given functional differential boundary value problems, using the technique of theorems about differential and integral inequalities and estimates of spectral radii of the corresponding compact operators in the space of essential bounded functions.
In this essay the author reflects on the subject of state-building, its interpretation and impact on the society. The government usually understands state-building differently than the opposition. The question is raised whether the development does not lead from state-building to “herd-building”, when smaller and larger groups behave like an easy-to-manipulate herd. But how can we revert this process?
We offer the quantitative estimation of stability of risk-sensitive cost optimization in the problem of optimal stopping of Markov chain on a Borel space X. It is supposed that the transition probability p(⋅|x), x∈X is approximated by the transition probability p˜(⋅|x), x∈X, and that the stopping rule f˜∗ , which is optimal for the process with the transition probability p˜ is applied to the process with the transition probability p. We give an upper bound (expressed in term of the total variation distance: supx∈X∥p(⋅|x)−p˜(⋅|x)∥) for an additional cost paid for using the rule f˜∗ instead of the (unknown) stopping rule f∗ optimal for p.
Treaty provisions on the free movement of persons do not directly address free movement of family members. The right to move to and reside in another Member State for family members of the moving EU citizens is anchored in the secondary law, namely in the Directive 2004/38. However, the Court of Justice, under certain circumstances, grants the right of residence for family members-third country nationals outside the scope of the Directive, even in the Member State of the EU citizen’s nationality, by virtue of different Treaty provisions. That brings a lot of inconsistency, legal uncertainty and, in the end, risk of injustice. This article summarizes the different legal sources of residence right for family members-third country nationals in that internal situation as adjudicated by the Court of Justice until nowadays and assesses on that background whether the time is ripe for an amendment of the Directive 2004/38.
The authors look into a current topic – history and present of the legal implementation of the right to strike in the Czech Republic. They introduce pieces of legislation that to some extent governed this right in the past and continue to govern it today. An important law, which established the right to strike during the Austrian-Hungarian period was the coalition act from 1870. This act was received in the Czechoslovak legal system by receiving standard No. 11/1918 Col. The article then chronologically introduces other pieces of legislation up until the present, when the fundamental document for the right to strike is the Charter of Fundamental Rights and Freedoms and the Act No. 2/1991 Col. on collective bargaining. However, a law governing strikes outside of collective bargaining is still missing. This should be fixed.
Shown an approach to the calculation of anisotropic plates numerically-analytical boundary elements method. The two-dimensional problem is reduced to one-dimensional by variation method Kantorovich-Vlasov. To select a function of the transverse distribution of deflecitons are encouraged to use one of two methods - dynamic or static. Application of numerical and analytical boundary element method allows a single approach to obtain the solution of basic differential equation of bending of anisotropic plate with any boundary conditions and without any restrictions on the nature of the application of the external load. and Obsahuje seznam literatury
