Аннотация:The paper is devoted to the study of Nijenhuis operators of arbitrary dimension$n$ in a neighborhood of a point at which the first $n-1$ coefficients of thecharacteristic polynomial are functionally independent, and the last coefficient(the determinant of the operator) is an arbitrary function. We prove a theoremon the general form of such Nijenhuis operators, and also obtain their completedescription for the case in which the determinant has a nondegeneratesingularity.
