We characterize the structure of the domain of a pure jump-type Dirichlet form which is given by a Beurling–Deny formula. In particular, we obtain su cient conditions in terms of the jumping kernel guaranteeing that the test functions are a core for the Dirichlet form and that the form is a Silverstein extension. As an application we show that for recurrent Dirichlet forms the extended Dirichlet space can be interpreted in a natural way as a homogeneous Dirichlet space. For reflected Dirichlet spaces this leads to a simple purely analytic proof that the active reflected Dirichlet space (in the sense of Chen, Fukushima and Kuwae) coincides with the extended active reflected Dirichlet space. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

The thesis deals with recent Czech translations of children's poetry in English and their addressees. In the first part, we describe the terminological issues related to the terms dětská literatura and dětská poezie (and their English equivalents), focus on the specific features of children's poetry and the process of translating children's literature, and finally outline the history of children's poetry in the Czech lands, the United Kingdom and the USA. In the second part, we compare target texts with their source texts in terms of content (proper nouns, puns etc.) and form (rhythm, rhyme etc.), thereby showing the strategies the translators used. Finally, we also comment on the issues pertaining to the publishing of children's literature and describe the origination of the Czech translation of Shel Silverstein's A Light in the Attic.
