A complete characterization of Radon planes whose unit spheres are regular polygons
Kalidas Mandal, Debmalya Sain, Kallol Paul
We study the structure of the unit sphere of polygonal Radon planes from a geometric point of view. In particular, we prove that a -dimensional real polygonal Banach space $ \…

On two extremum problems related to the norm of a bounded linear operator
Debmalya Sain, Kallol Paul, Kalidas Mandal
We explore the norm attainment set and the minimum norm attainment set of a bounded linear operator between Hilbert spaces and Banach spaces. Indeed, we obtain a complete character…
