Abstract:

The complex Ldecomposability and the splitting operation were discussed. It has been proved that if the splitting operation is applied to a quadrant entry, the complex Ldecomposability remains the same.

Key words: matrix, complex sign, pattern, qualitative analysis, decomposability
