Non-projectivity and valency
We describe results of investigation of a specific type of discontinuous constructions, namely non-projective constructions concerning verbs and their arguments. This topic is especially important for languages with a relatively free word order, such as Czech, which is the language we have primarily worked with. For comparison, we have included some results for English. The corpora used for bot...
متن کاملTopological Transitivity and Strong Transitivity
We discuss the relation between (topological) transitivity and strong transitivity of dynamical systems. We show that a transitive and open self-map of a compact metric space satisfying a certain expanding condition is strongly transitive. We also prove a couple of results for interval maps; for example it is shown that a transitive piecewise monotone interval map is strongly transitive.
متن کاملTesting the Projectivity Hypothesis
The empirical validity of the projeetivity hypothesis for Bulgarian is tested. It is shown that the justification of the hypothesis presented for other languages suffers serious methodological deficiencies. Our automated testing, designed to evade such deficiencies~ yielded results falsifying the hypothesis for Bulgarian: the non-projective constructions studied were in fact grammatical rather ...
متن کاملProjectivity and freeness over comodule algebras
Let H be a Hopf algebra and A an H-simple right H-comodule algebra. It is shown that under certain hypotheses every (H,A)-Hopf module is either projective or free as an A-module and A is either a quasi-Frobenius or a semisimple ring. As an application it is proved that every weakly finite (in particular, every finite dimensional) Hopf algebra is free both as a left and a right module over its f...
متن کاملLinear codes from projectivity groups
In this talk, we consider linear error–correcting codes that are constructed from orbits of a projectivity group of PG(k, Fq). In this way, we obtain linear codes with better parameters with respect to the previously known ones, and improve several entries in MinT’s tables (http://mint.sbg.ac.at/) and Markus Grassl’s Tables (www.codetables.de). Among these new codes, we found of particular inte...
