Non-associative algebras and applications to digital data transmission
- Speaker: Susanne Pumpluen
- The University of Nottingham, UK
- Time: June 7th 2022
We look at a class of nonassociative algebras that can be defined using skew polynomials, and discuss their structure and applications. These algebras can be seen as canonical generalizations of central simple algebras, and some behave surprisingly similar to their classical "cousins". They are employed to build codes used for wireless digital data transmission, e.g. in mobile phones, laptops or portable TVs. To make the talk accessible to a broad audience, we will explain the main ideas using the example of Hamilton's quaternion algebra. We will explain how to generalize the construction of Hamilton's quaternion algebra to nonassociative four-dimensional algebras, and how to use them in space-time block coding.
(p,q) arithmetic Klienian Group
- Speaker: Kaywan Salehi
- Massey University, New Zealand
- Time: May 7th, 2022.
Arithmetic Kleinian group is an important branch of low dimensional geometry and topology. One of the significant side of it, is two generating arithmetic groups. In our research, we will complete Maclaclan and Gaven martin work for all possible Arithmetic groups which generated by two elements $(f; g)$ of order $(p; q)$. They calculated $(p; q)$- cases for $p; q < 6$. But for $p; q < 6$, cases still have remainded. Here we try to introduce some Theorems and Methods to complete our work.

For two Banach algebras A and B and a nonzero multiplicative linear functional ϴ on B, Monfared introduced the ϴ-Lau product B. In this paper, we investigate and study the notions of ϕ-biprojectivity, ϕ-biflatness and ϕ-Johnson amenability of B and their relations with A and B. As an application, we characterize ϕ-biflatness and ϕ-biprojectivity for ϴ-Lau product of Banach algebras related to locally compact groups and discrete semigroups.
Post-Quantam Secure Communications
- Speaker: Wrya Karim Kadir
- University of Bergen, Norway.
- Time: March 9th, 2022
Imagine a mature enough quantum computer is available in the near future. What can it do? There are several tasks for which a quantum computer will be useful. It can also be a threat to our privacy. The one that is mentioned most frequently is that quantum computers will be able to read secret messages communicated over the internet using the current cryptographic schemes. Which simply means that none of us would be able to securely and privately communicate via internet if we stay with our current online devices. In this talk we will address this issue. We will also describe the actions that we can do in advance in order to stay secure in the world with quantum computers.
