A collection of research papers, both new and expository, based on the interests of Professor J. P. C. Greenlees.
Scott Balchin is currently Postdoctoral Fellow at the Max Planck Institute of Mathematics in Bonn. Previously he was Postdoctoral Research Fellow at the University of Warwick. He has published several articles on the use of Quillen model categories in homotopy theory and is the author of A Handbook of Model Categories (2021). David Barnes is Senior Lecturer in Mathematics at Queen's University Belfast. His research focuses on stable homotopy theory, usually with either a monoidal or equivariant flavour, often using algebra to describe the structures in question. He is a co-author of Foundations of Stable Homotopy Theory (2020). Magdalena Kedziorek is Assistant Professor in Mathematics at Radboud University in Nijmegen. She has held research positions in the Netherlands, Germany, the United Kingdom and Switzerland, where she has worked on topics including rational stable homotopy theory, equivariant operads and motivic homotopy theory. Markus Szymik is Professor of Mathematics at NTNU Norwegian University of Science and Technology in Trondheim. His research interests center around algebraic and geometric aspects of symmetry. He has written an introductory textbook on topology (2009 and 2015) and co-edited a conference proceedings on topological data analysis (2020).
