RUDN scientists proved a theorem that would help calculate water movement in porous rock

Mathematicians from RUDN University have proved a unique continuation theorem for a one dimensional solution to a fractional order diffusion problem, which can help calculate water movement in porous rock. The results of their work are needed for more accurate analysis and numerical simulation of solutions.

Army scientists develop computational model to predict human behavior

Researchers developed a new dynamic model that quantitatively incorporates group behavior into individual decision-making, predicting the sensitivity of individuals to persuasion and deception. The model uses non-integer derivatives to compress the influence of groups into a single parameter.

Calculating a new theory: How to teach an old field new tricks

A team of mathematicians from the University of Averio combined past and future operators to create a new theory for fractional calculus, which can predict how variables change and react. This breakthrough has implications for various technologies and applications, including information exchange and automation.
