Abstract
This paper analyzes the geometrothermodynamics of charged anti-de Sitter (AdS) black holes with a global monopole using Tsallis statistics, a non-additive generalization of Boltzmann-Gibbs entropy. The study examines the impact of Tsallis entropy on small-large black hole phase transitions and critical exponents, comparing the findings to liquid-gas phase changes in van der Waals fluids. Physical constraints on the Tsallis parameter and its effect on black hole radiation sparsity are discussed. Thermodynamic curvature behavior is explored geometrically using the Ruppeiner formalism, and similar considerations are extended to charged (2+1)-dimensional Banados-Teitelboim-Zanelli (BTZ) black holes.
