	Numerical solution of a temperature distribution problem in a body with uncertain heat conductivity coefficients Chleboun, Jan Time independent heat flow problems are considered. The heat conductivity coefficients depend on temperature and are not known exactly. The goal is to find the maximum reachable temperature in a fixed test subregion if coefficients are taken from certain compact admissible set. Results of the sensitivity analysis for isotropic as well as anisotropic bodies are given together with results of numerical examples. Detailed record
	Sobolev inequality with variable exponent Rákosník, Jiří Recently, an increasing attention has been payed to partial differential equations and variational integrals involving coefficients of nonstandard growth. A natural tool to handle some of the related problems may be theory of spaces of functions integrable with variable exponent. The paper discusses the Sobolev inequality in this context and shows that it holds if the exponentfunction is Lipschitz-continuous. Detailed record
	Supremum operators and optimal Sobolev inequalities Pick, Luboš We study the problem of optimality of rearrangement-invariant norms for which a Sobolev-type inequality holds. A key role is played by a Hardy-type operator involving supremum. Detailed record
	On boundedness of fractional maximal operators between classical Lorentz spaces Opic, Bohumír We characterize the boundedness of fractional power-logarithmic maximal operators between classical Lorentz spaces. Detailed record
	Approximation numbers of Hardy-type operators on trees Harris, D. J. ; Lang, Jan We present upper and lower estimates and an asymptotic result for the approximation numbers of the Hardy-type operator on a tree gama. The results include compactness criteria for the Hardy-type operator. Detailed record
	On some properties of the class P ( B, b, alfa ) Fuka, Jaroslav ; Jakubowski, Z. J. Detailed record
	The principle of the finite element method Křížek, Michal Detailed record
	Natural operators on the bundle of Cartan connections Panák, Martin Detailed record
	How do students understand properties of the concepts of distance and area in mathematical and real contexts? Barešová, Monika ; Weislová, E. Detailed record
	Towards developing teachersďability for grasping situations Tichá, Marie ; Koman, M. Detailed record
