Title: Sarita Rosenstock (ANU)
Title: A Category Theoretic Framework for Physical RepresentationAbstract:
It is increasingly popular for philosophers of science to use category
theory, the mathematical theory of structure, to adjudicate debates about
the (in)equivalence of formal physical theories. In this talk, I discuss
the theoretical foundations of this strategy. I introduce concept of a
“representation diagram" as a way to scaffold narrative accounts of how
mathematical gadgets represent target systems, and demonstrate how their
content can be effectively summarised by what I call a “structure
category". I argue that the narrative accounts contain the real content of
an act of physical representation, and the category theoretic methodology
serves only to make that content precise and conducive to further
analysis. In particular, one can use tools from category theory to
assess whether one physical formalism thus presented has
more "properties", "structure", or "stuff" than another. NB: Tea at
