The first is a recent basic modal logic developed to analyze balance theory. We examine different extensions to its language to define previously undefinable frame properties and introduce distance measures to evaluate how far a network is from polarization. Then a novel two-sorted hybrid logic of strong and weak ties will be presented. We see that a known claim from social network analysis is a validity and relate it to echo chamber formation. We will also talk about threshold models, an epistemic modality and dynamic operators in this logical framework.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Mina Young Pedersen<br \/>\nDate and Time: Thursday, March&nbsp;19th 2020, 16:30-18:00<br \/>\nVenue: ONLINE<br \/>\nTitle: \u00a0Logical analyses of polarization and echo chambers<br \/>\nAbstract.<br \/>\nRecent literature has shown a growing interest for research in the interplay between logic and social network theory.
