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.
