Title: A general and unifying construction for semifields and their related maximum rank distance codes
Abstract : Semifields are algebraic structures that can be for instance used to construct nondesarguesian planes in finite geometry, as well as maximum rank distance (MRD) codes with special parameters (more precisely, every element in the code will be a square matrix with full rank). Many constructions of MRD codes are rooted in ideas from semifield theory. Interestingly, many known constructions of semifields only exist in even dimension (i.e. the dimension over the prime field is even), leading to MRD codes in even dimension or MRD codes in odd dimension over a field of even degree. In this talk, we present a unifying construction for almost all semifields of this type, including semifields found by Dickson, Knuth, Hughes-Kleinfeld, Taniguchi, Dempwolff, Bierbrauer, Zhou-Pott in the last 120 years. Our construction recovers all these semifields, and gives many new examples.

Speaker: Merve Karabulut, Florida Atlantic University
Title: Number Theoretic Transform: A Python-based Speed Enhancement
Abstract: Our proposal involves a Python-based solution that utilizes Numba's just-in-time compilation capabilities. We aim to optimize the control flow of the Number Theoretic Transform (NTT) operation to exploit parallelism in modern CPUs. Our solution leverages multi-core processing, multi-threading, and cache memory.
Speaker biography: Merve is a computer engineering graduate from Yildiz Technical University, with experience in full-stack development and blockchain, especially with Hyperledger. At FAU, she is working towards a Ph.D., focusing on PQC with Dr. Reza Azarderakhsh. Her goal is to create secure solutions resistant to quantum computing and efficient implementation of algorithms.
