Let L ( X , Y ) denote the class of linear transformations T : D ( T ) C X ---t Y where X and Y are normed spaces. A quantity f is called densely invariant if for every system L ( X , Y) and every operator T E L ( X , Y ) we have f ( T I E ) = f ( T ) whenever E is a core of T. The density invar

## Abstract The present paper is the first one in a series of two papers devoted to a unified approach to the problem of completeness of the generalized eigenvectors (the root vectors) for a specific class of linear non‐selfadjoint unbounded differential operators. The list of the problems for whic
