Umamaheswaran Arunachalam (b.1982) has a research contract at the Harish-Chandra Research Institute (HRI) in Allahabad, India. His research proposal was about the structure of quantum cluster algebras and generalized weyl algebras with tate homology of modules. He was hosted by Professor Bernhard Keller of the UFR de Mathématiques, Université Paris Diderot, France during the period 01.09.2019-30.09.2019.

This activity was supported by a grant from the Niels Henrik Abel Board (Norway).

Mina Bigdeli (b. 1985) is a Postdoctoral Fellow at the Institute for Research in Fundamental Sciences (IPM) in Teheran, Iran. The main goal of her research proposal is to translate Reisner's criterion for Cohen-Macaulayness from Stanley-Reisner complexes to facet complexe; a subject in the interplay between combinatorial geometry and algebraic topology. She was hosted by Professor Sara Faridi of the Department of Mathematics and Statistics, Dalhousie University at Halifax, Canada, from October 29, 2021 - December 14, 2021.

This activity will be supported by a grant from the Niels Henrik Abel Board (Norway).

Khadijeh Nedaiasl (b.1985) is Assistant Professor at the Institute for Advanced Studies in Basic Sciences at Zanjan, Iran. The main goal of her research proposal was to study the numerical solutions of volume integral equations by discrete dipole approximation. She was hosted by Professor Martin Costabel of IRMAR, Institut Mathématique Université de Rennes 1, France from September 1, 2022 – October 31, 2022.

This activity will be supported by a grant from the Niels Henrik Abel Board (Norway).

Nguyen Thac Dung (b. 1980) is Associate Professor at Hanoi University of Science, Vietnam National University. The main goal of his research proposal is to use Hodge-Laplacian to investigate elliptic and parabolic problems in curved manifolds and in smooth metric measure spaces. He was hosted by Professor Guofang Wei of the Department of Mathematics, University of California at Santa Barbara, USA from July 15 - August 14, 2022.
