A series of talks by Mihai Putinar(Newcastle University, UK), at the Department of Mathematics, Indian Institute of Science, Bangalore

Both series were delivered at the Department of Mathematics, Indian Institute of Science, Bangalore. They were livestreamed and recorded, attracting hundreds of views on YouTube.

Scholar Visits

Professor Apoorva Khare visited Plymouth University, UK, for a month.

Dr. Abhay Jindal visited King's College London as part of the SPARC-supported collaboration.

Dr. Prateek Kumar Vishwakarma visited Plymouth University, UK, through SPARC support.

During this visit, he carried out part of the research that later led to a publication in the Journal of Algebra and an extended abstract accepted at FPSAC 2025. He expresses sincere gratitude for the support provided through the SPARC grant and fondly recalls his time in the UK.
