below.----------A Category Theoretic Framework for Physical
RepresentationSarita Rosenstock (ANU)Abstract: 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 the
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 according to a given narrative about how they both
purport to represent the same physical systems. ----------Hi there,
