On the Structural Rank Function: A Corrected Approach

This work introduces the structural rank function η(k), arising from a novel approach to divisor structure analysis in modular arithmetic. Unlike classical multiplicative functions, η(k) measures the "distance" between complementary divisors, providing new insights into the distribution of arithmetic functions. This package includes the corrected research article, experimental data for k ≤ 10^6, and complete Python implementation.
