Generalizations of Alladi’s formula for arithmetical semigroups

Time: 10/21 Fri. 3:00-3:50 PM
Location: On zoom or at DH 249.
Speaker: Ning Ma from SUNY Buffalo
Abstract: In this talk, we will discuss a general version of Alladi’s formula with Dirichlet convolution holds for arithmetical semigroups satisfying Axiom A or Axiom A^#. As applications, we apply our main results to certain semigroups coming from algebraic number theory, arithmetical geometry and graph theory. This is a joint work with Lian Duan and Shaoyun Yi.
