Lashi visits European research centres

Lashi Bandara was invited to visit number of research centres in Europe (Germany, Sweden, United Kingdom and Portugal) from mid-December 2025 till mid-February 2026.
Three weeks of his time was visiting the Geometry group at the University of Potsdam under the invitation of Christian Bär, Professor of Geometry.
He spent a week at the University of Rostock on invitation by Volker Branding, Professor of Analysis.

He began a collaboration with Volker and mutual collaborator and colleague Georges Habib from the Lebanese University to study spin-Dirac operators in low-regularity settings.
Lashi also delivered the Mathematics Colloquium there, and signed their colloquium book.

He visited Eva-Maria Hekkelman, currently a postdoc at the Max-Plank Institute for Mathematics in Bonn to continue work on their project in collaboration with Ed McDonald, currently a postdoc at Universite Paris-Est Créteil on spectral triples for rough metrics.
Lashi also gave a talk in the Global Analysis and Operator Algebras seminar at the University of Bonn.

Lashi visited Magnus Goffeng at the University of Lund. He delivered a talk in the Partial Differential Equations seminar and he was also invited to speak in the Pedagogical Colloquium, where he gave a talk titled Co-constructive mastery based learning in mathematics. His discussions with Magnus during his one-week visit led to a new project which they have begun to pursue.

His Swedish trip ended with a visit to Alberto Richtsfeld, currently a postdoc at Stockholm University, to finish their work on an index formulae for the Rarita-Schwinger operator on manifolds with boundary. He also gave a talk at KTH Stockholm and interacted with his colleagues Oliver Petersen and Klaus Kröncke, respectively Professors at SU and KTH.
Lashi visited Brunel University of London and was delighted to be able to discuss mathematics with his PhD student Anisa Hassan, at Brunel, on his old chalkboards.
His trip to the UK culminated in a visit to Ali Taheri, Professor of Analysis at the University of Sussex where he also delivered a talk in the analysis seminar.
Lashi’s final visit was for one-week to the University of Aveiro to visit Paula Cerejeiras and Uwe Kähler, both Professors in complex analysis.

Mathematics at Aveiro has a beautiful metal sculpture of important mathematical quantities as featured in the picture below.
He gave a talk on his recent work on boundary value problems and spent time in discussions with Paula, Uwe and also Simão Lucas, currently a PhD student at Politecnico di Milano. These discussions ranged from discussions on boundary value problems to recent work on Hodge-decompositions for non-smooth metrics as well as the study of the set of all non-smooth metrics. They have begun preliminary analysis for a project on inverse problems.
Lashi was also made an editor for the journal Applied Analysis and Clifford Algebras, a journal under Springer-Nature.

On his return home, Lashi enjoyed working on some of the maths that was discussed with his collaborators in the tropical garden, called the Orchard, at Doha Airport!
