The role of Sommerville tetrahedra in numerical mathematics
 Hošek, Radim
In this paper we summarize three recent results in computational geometry, that were motivated by applications in mathematical modelling of fluids. The cornerstone of all three results is the genuine construction developed by D. Sommerville already in 1923. We show Sommerville tetrahedra can be effectively used as an underlying mesh with additional properties and also can help us prove a result on boundary-fitted meshes. Finally we demonstrate the universality of the Sommerville's construction by its direct generalization to any dimension.

This bachelor thesis emanates from the paradox that undergraduate students of economics are given a number of mathematical courses that endow them with powerful tools, which are not afterwards used in the courses of economics and finance. The goal of this thesis is to provide a supplementary explanation of some of these topics, using various mathematical tools that are contained in the standard courses. Special attention is given to the problematics of graphical representation in economics, as in many cases there is a tendency to disobey the standard convention of using the horizontal axis for the independent variable. For some topics an alternative graphical visualisation is supplied while we show that it is not always useful. We investigate the issue of summing the curves and offer an explanation, how the information can be obtained from the graphs that do not obey the above mentioned convention.
