Arsenii Sagdeev

Dr. Arsenii Sagdeev is a Postdoctoral Researcher at Karlsruhe Institute of Technology (KIT) within the Department of Mathematics, specifically affiliated with the Research Group Discrete Mathematics under the supervision of Prof. Dr. Maria Axenovich. His office is located in Kollegiengebäude Mathematik (20.30), Room 1.045, with regular office hours on Tuesdays from 13:00-14:00. He actively contributes to the academic community through seminar organization and course instruction.

His research centers on extremal combinatorics, Ramsey theory, discrete geometry, and graph theory, with particular emphasis on geometric variants of Ramsey problems, structural properties of geometric graphs, and combinatorial configurations in normed spaces. His work frequently explores monochromatic structures in metric spaces, packing densities, and extremal graph parameters in geometric settings.

Recent publications (2023-2025) demonstrate consistent output in high-impact combinatorial geometry, with significant focus on max-norm and Chebyshev metric spaces. Key themes include monochromatic configurations in Minkowski planes, extremal properties of ordered geometric graphs, and solutions to classical combinatorial problems like Borsuk's conjecture variants. His research bridges theoretical combinatorics with geometric applications, often yielding tight bounds for extremal quantities.

He serves as organizer for both the AG Discrete Mathematics seminar and the Seminar Euclidean Ramsey theory for Winter Semester 2025/26. His teaching portfolio includes Modern Methods in Combinatorics (Summer 2025) and Extremal Graph Theory (Winter 2024/25), reflecting his research expertise. Current institutional engagement includes active participation in KIT's Institute of Algebra and Geometry through the Discrete Mathematics research group.
