The Fractional SI Reaction–Diffusion Model with Incommensurate Orders: Stability Analysis and Numerical Simulations

open access: yesFractal and Fractional
In this work, we present a fractional-order reaction–diffusion model for the spread of infectious diseases, incorporating incommensurate Caputo derivatives to capture memory effects and heterogeneous temporal behavior across compartments.

An Efficient and General Ascending Menu Auction under Budget Constraints

open access: yesJournal of Mechanism and Institution Design
An auctioneer wishes to sell multiple heterogeneous indivisible items to several bidders. Every bidder can demand several items, have complex preferences and faces a hard budget constraint. In this setting, Walrasian equilibria may fail to exist.
