Nízke Tatry (Slovensko : pohorie) Language Slovak Country Slovak Republic systematics 502 Annotation We have described the spatial distribution of destructive morphogenetic form above the timberline and their functional dependence on selected landscape-ecological factors of alpine areas. Ďumbierske Tatry Mts. are the western part of Nízke Tatry Mts. situated in the central Slovakia. Model territory has some 9500 hectares where 698 hectares of destructed morphogenetic forms had developed. The common signs of their distribution are presence on N, NW and S exposition, on slopes steeper than 25°, in elevation higher than 1600 m a. s. l. and were created on deluvial sediments – coarse-grained debris. Typical soils are podzols and lithosols or rankers, ergo sandy-loams and loamy sands Public work category ADF No. of Archival Copy 31854 Catal.org.

Source document Mathematics of Computation. Vol. 81, no. 277 (2012), pp. 569-583. - Providence : American Mathematical Society, 2012 Keywords polyhedron Archimedean solid surfaces groups graph embedding regular maps Cayley maps genus Language English Country United States of America systematics 51 Annotation The paper focuses on the classification of vertex-transitive polyhedral maps of genus from 2 to 4. These maps naturally generalise the spherical maps associated with the classical Archimedean solids. Our analysis is based on the fact that each Archimedean map on an orientable surface projects onto a one- or a two-vertex quotient map. For a given genus g>= 2 the number of quotients to consider is bounded by a function of g. All Archimedean maps of genus g can be reconstructed from these quotients as regular covers with covering transformation group isomorphic to a group G from a set of g-admissible groups. Since the lists of groups acting on surfaces of genus 2,3, and 4 are known, the problem can be solved by a computer-aided case-to-case analysis Public work category ADC No. of Archival Copy 22535 Repercussion category PISANSKI, Tomaz - WILLIAMS, Gordon - BERMAN, Leah Wrenn.
