Anna Bellomo | Bolzano, Collections, Sets and Infinity

Anna Bellomo presented her ongoing PhD research on Bolzano’s conceptions of infinity, as well as her involvement on the e-Ideas framework.

‘In the philosophy of mathematics circles, Bernard Bolzano (1871-1848) is mostly known for two things: his contributions to the so-called rigorisation of analysis, and his proto-Cantorian theory of size for infinite sets. In this talk, I will focus on the latter and summarise some recent findings suggesting that, contrary to what has been so far the default interpretation of Bolzano’s treatment of the countable infinite, his focus was not a theory of size for infinite sets, but solving some problems relating to the treatment of (non-convergent) infinite sequences.’
