Discrete Mathematics and Geometry

Discrete Mathematics Working Group (Arbeitsgemeinschaft Diskrete Mathematik, AGDM)

Info: The AGDM seminar is a joint seminar of the University of Vienna and TU Wien. In winter semesters, we meet on Tuesdays from 15:00 to 16:30 at the University of Vienna. In summer semesters, the seminars are held in TU Wien.

From 2025, we will be using a new mailing-list to advertise the seminar. You can register here.

Place: TU Wien (Freihaus, Wiedner Hauptstr. 8-10, 1040 Wien): Room DA 08 B19 (Dissertantenzimmer), 8th floor, Tower A (green)

Time: Tuesday, 15:15-16:45

Title: Dual transform, PSD codes and self-dual bent functions
Speaker: Stefka Bouyuklieva (University of Veliko Tarnovo)
Abstract: The relationship between different types of linear codes is analyzed through (projective) dual transformation. The considered codes are represented by a generator matrix or characteristic vector, and the dual transform is defined in these terms. The aim is to study projective self-dual and self-polar codes and their relations with Boolean functions. Self-polar codes are a special class of projective self-dual codes and are closely related to self-dual and anti-self-dual bent functions.

Code of conduct

Maintaining a respectful environment is essential to fostering meaningful dialogue and intellectual growth. Participants are expected to refrain from any form of disrespectful or inappropriate behaviour, including offensive comments, harassment, or disruptive conduct. Questions and contributions should be constructive, relevant to the topic, and posed in a professional manner that encourages healthy academic exchange. Harassment of any kind—whether verbal, non-verbal, or physical—will not be tolerated, and all attendees are urged to uphold these principles to ensure a safe and welcoming atmosphere for everyone.
