Sophie Libkind

Postdoctoral Researcher

Topos US

Sophie Libkind received her PhD in Math from Stanford University in 2024. Her research is motivated by connections between continuous dynamics occurring in nature and symbolic computation. Sophie is also passionate about education both in terms of redefining what it means to “be a math person” as well as bridging the languages of math and science.

Poly @ Work 2024
Polynomial functors are a prime example of mathematics’ startling capacity to yield deep formal insights and real-world applications from the simplest ingredients. The category of polynomial functors (Poly) offers an abundance of elegant theory linked with computational design patterns that span…

Composing springs

Physical systems are often composed of many interacting subsystems. In this post, we take a peek at the math and the software implementation for composing systems of springs using decorated cospans.

A Rosetta Stone for our vignettes

Trustworthy Reification
Not all meals created from the same recipe are equally delicious. Not all programs that accurately sort a list are equally useful. High-level specifications, such as a recipe or a prompt, are only practical because I trust the chef or engineer to execute them in a way that aligns with my values…

“Cells that fire together, wire together.” This slogan for Hebbian learning evokes a strategy for reorganization in which an individual strengthens their connection with another if they have similar behavior. Here we give a mathematical account of Hebbian learning as a dynamic monoidal category.
