| Title | On the embeddability of skeleta of manifold triangulations |
| Place | Room E408, Science Building E, Sugimoto Campus & Zoom |
| Abstract | It is well known that every finite d-dimensional simplicial complex can be embedded in R^{2d+1}. On the other hand, by the classical van Kampen-Flores theorem there exists a finite d-dimensional simplicial complex that cannot be embedded in R^{2d}. In this talk, we discuss the embeddability of the d-skeleton of simplicial complexes obtained as triangulations of manifolds, into R^{2d}. This is joint work with Daisuke Kishimoto (Kyushu University). |

| Title | Statistics in Number Theory |
| Place | Room E408, Science Building E, Sugimoto Campus & Zoom |
| Abstract | Many basic objects in number theory, such as prime numbers, do not follow any regular patterns. However, they typically obey certain statistical laws - some of which are less obvious than others. I will first discuss some aspects of the distribution of prime numbers, explaining how they behave like random numbers in some ways but not others. Then I will discuss the distribution of other key objects in number theory, namely elliptic curves and modular forms. |
