Strong Ramadanov Conjecture for Real Ellipsoids in $C^{2}$ : two approaches

Jan Gregorovic, Ilya Kossovskiy, Son-Ying Li +1

In this paper, we provide two (significantly different) proofs of the well known Strong Ramadanov Conjecture for the class of real ellipsoids in the complex $2$ -space.

On the Beloshapka's rigidity conjecture for real submanifolds in complex space

Jan Gregorovic

A well known Conjecture due to Beloshapka asserts that all totally nondegenerate polynomial models with the length $l \geq 3$ of their Levi-Tanaka algebra are {\em rigid}, that is,…
