Jurisdiction and applicable law in cases of damage from space in Europe—The advent of the most suitable choice—Rome II

2010

Liability for space activities is a much discussed subject and the advent of commercial space operations has only added to its importance. Articles VI and VII Outer Space Treaty, together with Articles II and III Liability Convention, remain the main entry level for state liability for damage arising from private space activities. Few space-faring nations have introduced national space statutes that include a flow down of their international obligations. The European Union (EU) Regulation on the law applicable to non-contractual obligations—hereinafter Rome II Regulation—could harbour developments for liability law in the context of damage resulting from space operations. Space activities w…

From subatomic to immense: About the possible influence of the Theory of Relativity and Quantum Mechanics in the fantastic

2015

The fantastic is based on three pillars: reality, the impossible and fear. Theoretical physics is a branch of science that has deeply studied reality, from the subatomic world to the immensity of outer space. In this article, we want to study how the Theory of Relativity and the Quantum Mechanics have influenced the configuration of the fantastic, and in addition, we want to verify if these branches of physics are capable of explaining certain fantastic phenomena.

Prawo kosmiczne w kontekście trzech reżimów prawnych. Jedność celów czy egoizm interesów?

2021

W artykule zaprezentowano aktualne kwestie związane z wykorzystaniem przestrzeni kosmicznej wraz ze wskazaniem konieczności przestrzegania obowiązujących regulacji, współtworzących międzynarodowe prawo kosmiczne. Zaprezentowano swego rodzaju proces ‒ ewolucję wykorzystywania przestrzeni kosmicznej, począwszy od monopolu państw, przez zdefiniowane wolą państw działania organizacji międzynarodowych, kończąc na narodowych agencjach kosmicznych, będących instytucjonalnym wsparciem również dla prywatnych podmiotów. W pracy, adekwatnie do wykazanej wielopodmiotowości, prezentuje się regulacje prawne, w których pierwsze konwencje, umowy z lat 60. i 70. XX w., współtworzące międzynarodowe prawo kos…

Automorphisms of 2–dimensional right-angled Artin groups

2007

We study the outer automorphism group of a right-angled Artin group AA in the case where the defining graph A is connected and triangle-free. We give an algebraic description of Out.AA/ in terms of maximal join subgraphs in A and prove that the Tits’ alternative holds for Out.AA/. We construct an analogue of outer space for Out.AA/ and prove that it is finite dimensional, contractible, and has a proper action of Out.AA/. We show that Out.AA/ has finite virtual cohomological dimension, give upper and lower bounds on this dimension and construct a spine for outer space realizing the most general upper bound. 20F36; 20F65, 20F28

Attività di impiego e di testing di armi anti-satellite e diritto internazionale

2022

Anti-satellite weapons (ASAT) are one of the major challenges to international security in the «Fourth Domain», namely outer space. This was proved by the test made by Russia in November 2021 and the reaction of the international community. The present testing of said arms against its own satellites, as well as the future and probable operating use of said arms against satellites of other States, raises the problem of their compatibility with international law. In particular, it is being debated in various international fora the legality of ASATs, whose use can generate space debris further congesting terrestrial orbits, thus interfering (and jeopardizing) the activities of other States.
