Sommario/riassunto |
|
This self-contained monograph explores a new theory centered around boolean representations of simplicial complexes leading to a new class of complexes featuring matroids as central to the theory. The book |

illustrates these new tools to study the classical theory of matroids as well as their important geometric connections. Moreover, many geometric and topological features of the theory of matroids find their counterparts in this extended context. Graduate students and researchers working in the areas of combinatorics, geometry, topology, algebra and lattice theory will find this monograph appealing due to the wide range of new problems raised by the theory. Combinatorialists will find this extension of the theory of matroids useful as it opens new lines of research within and beyond matroids. The geometric features and geometric/topological applications will appeal to geometers. Topologists who desire to perform algebraic topology computations will appreciate the algorithmic potential of boolean representable complexes. |

Sommario/riassunto |
|
More than 20 years have passed since the introduction of the Universal Character Set. However, legacy applications still cannot even render German umlauts correctly. Part of this problem is a hidden political agenda: Consciously or unconsciously, patterns of the Cold War are continued in the interaction between Western and Eastern European languages. This book examines the current use of diacritical marks in Western Europe, such as the use of names from Slavic languages in electronic data processing systems. The role of the media as multiplier receives particular attention, with most error examples taken from actual media coverage. Considering international, EU, and national law and referring to landmark court decisions, Kappenberg answers the question: 'Is there a right to diacritical marks in people's names?' This is followed by a description of current practice in several European countries. Finally, Setting Signs for Europe answers the question how in the framework of the EU's multilingualism policy, effective approaches can be created to raise awareness among software vendors, the media, government agencies, and individuals regarding the correct handling of diacritics. Kappenberg also assesses the use of diacritics as a style element and offers an improved input method for diacritics. |
