Ahmed Gossa

Licensed Civil Engineer Theoretical Researcher Biskra, Algeria

Independent researcher dedicated to the unification of differential languages through the Hierarchical Calculus framework.

Professional Background

Eng. Ahmed Gossa is a senior Civil Engineer officially accredited by the Algerian Ministry of Housing, Urban Planning and the City. Practicing in the province of Biskra (Bentious, M'khadma), his work encompasses structural stability analysis, seismic design, and urban infrastructure projects.

His unique trajectory combines practical engineering methodologies with high-level mathematical abstractions. By bridging these two worlds, he has developed innovative ways to measure multi-order change in complex systems.

Scientific Archive (History of Work)

2011 — Proportional Calculus

Initial discovery of relative differentiation, where the derivative is redefined to measure proportional shifts rather than absolute increments.

D_{p} f(x) = \frac{x}{f(x)} \cdot \frac{df}{dx}
2012 — Logarithmic Calculus

Extended the research into higher-order tiers, providing the mathematical tools to analyze systems governed by logarithmic growth patterns.

\[ D_L f(x) = \frac{d (\ln f(x))}{d (\ln x)} \]
2025 — Hierarchical Unification

The formal publication of the Hierarchical Calculus framework, unifying all change languages into a consistent Rank-Degree system. DOI: 10.5281/zenodo.17917302.
