"Torsion points and concurrent exceptional curves on del Pezzo surfaces of degree one"
The blow up of the anticanonical base point on X, a del Pezzo surface of degree 1, gives rise to a rational elliptic surface E with only irreducible fibers. The sections of minimal height of E are in correspondence with the 240 exceptional curves on X. A natural question arises when studying the configuration of those curves :

"The canonical divisor and properties of Cartier divisors for horospherical varieties"
We will discuss criteria for Cartier divisors to be base point free or ample. We will also give a formula for the canonical divisor. We will include many examples.
This seminar will be held jointly online and in person:

"Brun's Sieve and it's applications to the Twin Prime Conjecture"
For hundreds, if not thousands of years, people have been trying to work out whether or not the Twin Prime Conjecture is true. However, it wasn't until the early 1900s when Viggo Brun introduced his sieve that real progress towards the conjecture was made. This talk will introduce Brun's Sieve and use it to show some of the earliest steps that were made towards proving the Twin Prime Conjecture.
