Keywords Quantified Modal Logic and Proof Theory
Report I conducted a research stay at the Central European University (CEU) from January 2024 until March 2024, hosted by Prof. Dr. Ben-Yami. I investigated his newly developed logic for quantification, which is much closer to natural language than any other available contemporary system. I combined it with modal logic, another branch of formal logic that studies the deductive behaviour of words like 'necessarily' and 'possibly'. I developed five proof systems and demonstrated their strong soundness and completeness over a variety of semantics. As such, the entirety of the originally planned research project was carried out. This allowed me to complete a crucial subproject of my dissertation, which already resulted in invitations to conferences and two full papers. Moreover, I was further able to make many contacts with other researchers of similar interests in Vienna, both inside and outside the CEU. Prof. Ben-Yami has also agreed to be a member of my PhD comittee, and expressed strong interest in supervising me as a postdoc in the future. Thus, the research stay was a complete success. It would not have been possible without the RUB Research School's generous funding, however. I am greatful and indebted to the Research School for financing my stay, and wholeheartedly recommend all PhD students to apply for PR.INT-funding as well. It has immensly strengthened my own research projects, my career, personal network and even my appreciation for my own work.
