An intern researcher Yuri Kazakov gave a talk

On September 27, Yuri Kazakov made a presentation "Dynamic Epistemic Approaches to Solving the Surprise Exam Paradox" at the workshop "From the Logical Point of View".

Abstract

The surprise exam paradox is one of the most famous epistemic paradoxes which has more than 1,000 related publications. During my presentation, I will focus on describing the epistemic branch of approaches to formalizing this scenario. Its most influential representative is J. Gerbrandy, who proposed using PAL (Public Announcement Logic) to define a "surprise" in the exam scenario. The talk will discuss the connection of the surprise exam paradox with Moore-type sentences, the ability of dynamic epistemic logic to capture the essence of the paradox and the impact it can have on our understanding of knowledge as such.
