Konvergence ke stacionárním řešením bistabilní rovnice s nehladkým reakčním členem, které mají vyšší energii

In this paper, we investigate the local stability of critical points with energy that is higher than the ground-state energy of the functional associated with the bistable equation. We assume that a double-well potential lacks C^2 regularity at the global minimizers. Previous work ...

Rychlá palatinální expanze ve smíšeném chrupu, stabilita

Aims: The study focused on the evaluation of changes in upper and lower dental arch following rapid palatal expansion (RPE) in mixed dentition and the expansion stability into the permanent dentition. Material: The first sample (HYRAX group) included 31 patients with RPE in mixed&#...

Anizotropní semipozitonové kvazilinaární úlohy

We present the existence of positive solutions for a degenerate (or singular) quasilinear equation in a ball or in the entire space. As differential operator we consider a weighted p-Laplacian with a continuous cofficient satisfying a mild integrability condition towards the boundary of...

Některé překvapivé vlastnosti radiálních a symetrických vlastních čísel a funkcí p-laplaciánu na kruhu

We discuss several properties of eigenvalues and eigenfunctions of the p-Laplacian on a ball subject to zero Dirichlet boundary conditions. Among main results, in two dimensions, we show the existence of nonradial eigenfunctions which correspond to the radial eigenvalues.

Některá kritéria diskrétnosti spektra pololineárního Sturmova-Liouvilleova problému čtvrtého řádu

We prove a necessary and sufficient conditions for discreteness of the set of all eigenvalues of half–linear eigenvalue problem with locally integrable weights. Our conditions appear to be equivalent to the compact embedding of certain weighted Sobolev and Lebesgue spaces.

Lyusternikova-Gravesova věta pro součet lipschitzovské funkce a mnohoznačného zobrazení

In a paper of 1950 Graves proved that for a function f acting between Banach spaces and an interior point x in its domain, if there exists a continuous linear mapping A which is surjective and the Lipschitz modulus of the difference f-A at x is sufficiently smal...

Tržní kalibrace pro model stochastické volatility s dlouhou pamětí

In this article, we study a long memory stochastic volatility model (LSV), under which stock prices follow a jump-diffusion stochastic process and its stochastic volatility is driven by a continuous-time fractional process that attains a long memory. LSV model should take into account&#...

Pětiúhelníková pokrytí roviny

Pentagonal tiling is a tiling or tessellation of the plane where each piece (tile) is a pentagon. We describe classification, history and some properties of pentagonal tiling.

Profilace u myší s obezitou indukovanou na základě diety a s diabetem 2. typu po léčbě s metforminem a vildagliptinu a jejich kombinací na základě metabolomické analýzy moči

Metformin, vildagliptin and their combination are widely used for the treatment of diabetes, but little is known about the metabolic responses to these treatments. In the present study, NMR-based metabolomics was applied to detect changes in the urinary metabolomic profile of a mouse&#x...

10-tough chordal graphs are Hamiltonian

Chen et al. (1998) proved that every 18-tough chordal graph has a Hamilton cycle. Improving upon their bound, we show that every 10-tough chordal graph is Hamiltonian (in fact, Hamilton-connected). We use Aharoni and Haxell’s hypergraph extension of Hall’s Theorem as our main tool.

Počítání hypermáp Jegoričovovou metódou

The aim of this paper is to find explicit formulae for the number of rooted hypermaps with a given number of darts on an orientable surfaces of genus at most three.

A variational approach to bifurcation points of a reaction-diffusion system with obstacles and neumann boundary conditions

Given a reaction-diffusion system which exhibits Turing's diffusion-driven instability, the influence of unilateral obstacles of opposite sign (source and sink) on bifurcation and critical points is studied. In particular, in some cases it is shown that spatially nonhomogeneous stationary solution...

Diastema mediale: vliv na atraktivitu úsměvu

The present work strives to answer the questions about the impact of diastema of different width and shape on the evaluation of smile attractiveness, and whether there are differences related to age and gender of evaluators, and differences between lay public and experts, and ...
