The study examines the legislative issues associated with providing a legal solution to the problem of the circus training of wild animals in the post-communist context. These issues are demonstrated using the example of the Czech Republic. In 2020, the country passed a comprehensive amendment to Act No. 246/1992 Coll. on the Protection of Animals Against Cruelty, which prohibits, among other things, the training of wild animals in circuses with effect from January 2022. The study focuses on the following research questions: What are the main determinants of the prohibition of wild animal training? and, What were the main arguments with respect to the wild animal training prohibition mentioned by politicians during the parliamentary debate? The data analysed here consist of parliamentary debates and texts presented by institutions advocating for or against the ban.
We introduce the two new concepts, productly linearly independent sequences and productly irrational sequences. Then we prove a criterion for which certain infinite sequences of rational numbers are productly linearly independent. As a consequence we obtain a criterion for the irrationality of infinite products and a criterion for a sequence to be productly irrational.
