CfR: Problem Posing: Aesthetical and Other Considerations, Duesseldorf, 3rd February 2023


How do mathematicians choose the problems they are engaging with? In what sense do they rely on aesthetical factors, and what is the role of the mathematical community? Moreover, what do these considerations tell us about the epistemology of mathematics? The workshop brings together scholars from philosophy, mathematics and mathematical education who investigate mathematical problem-posing.
