Values of the Epstein zeta function of a positive definite matrix and the knowledge of matrices with minimal values of the Epstein zeta function are important in various mathematical disciplines. Analytic expressions for the matrix theta functions of integral matrices can be used for evaluation of the Epstein zeta function of matrices. As an example, principal coefficients in asymptotic expansions of variance of the lattice point count in the random ball are calculated for some lattices.
This study examines how love was represented in late 18th century Czech fiction, as exemplified in the works of Antonín Josef Zíma and Prokop Šedivý. First we place Czech writing in its historical context with reference to contemporary French literature. We then focus on the formal features of works on love, discuss the influence of Sentimentalism on Czech culture, and finally consider the relationship between love and morality. Our study concludes that there is no evidence of originality in attitudes to love in late 18th century Czech fiction; instead, writers looked to foreign literatures for their themes. The resonance they produced in the Czech context, however, was different from that in countries with a richer literary tradition., Tomáš Dufka., and Obsahuje bibliografické odkazy
