The HLFF bids farewell to Sergei Novikov

We bid farewell to the mathematician Sergei Novikov, who passed away on June 6, 2024. He received the Fields Medal in 1970 "for important advances in topology, the most well-known being his proof of the topological invariance of the Pontrjagin classes of the differentiable manifold, including a study of the cohomology and homotopy of Thom spaces." We offer our sincere condolences to his family and friends.
