Constructing an Infinitesimal

Non-standard analysis involves working with infinitesimal real numbers — numbers smaller than $\frac{1}{n}$ for all $n$ but greater than $0$. In this talk, we will use ultraproducts to construct a non-standard model of the reals and give a description of infinitesimals in this model.

All graduate students are invited. As with all talks in the graduate student seminar, this talk will be accessible to all graduate students in math and stats.

This seminar was made possible by funding from the McGill mathematics and statistics department and PGSS.
