- World Report 2024: European Union (hrw.org)
European Union (EU) member states and institutions made new and renewed existing commitments to uphold and protect rights in 2023. In practice, however, the willingness of the EU to give effect to those commitments too often fell short, particularly when it came to the rights of people at its external borders and members of marginalized communities and in its response to the troubling spread of curbs on civil society.
- Empty set (Wikipedia)
In mathematics, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. Some axiomatic set theories ensure that the empty set exists by including an axiom of empty set, while in other theories, its existence can be deduced. Many possible properties of sets are vacuously true for the empty set.
