An Inertial Accelerated Predictor–Corrector Algorithm for Exponential Variational Inequalities with Sharp Convergence Guarantees and Applications

We study exponentially convex nonlinearities and exponentially monotone operators in Hilbert spaces for exponential variational inequalities (EVIs). We show that the exponential nonlinearity is the gradient of a convex functional, so it is monotone. We use this fact to prove existence, uniqueness, and contractivity of...

A Predictive Model of Currency Exchange Rates Based on Stochastic Fractional Power-Law Dynamics

This work proposes a stochastic fractional power-law model for currency exchange rate forecasting. The model incorporates nonlocal temporal effects through the Caputo fractional derivative and nonlinear scaling dynamics via a power-law formulation, providing a flexible framework for representing complex temporal behavi...
