Kiyoshi Ito

Kiyoshi Ito was a Japanese mathematician renowned for developing a rigorous way to analyze and understand systems involving randomness, such as stock markets or physical processes affected by chaos. He introduced what are called stochastic integrals and equations, which allow mathematicians to model and predict complex, unpredictable phenomena more accurately. His work provides foundational tools in probability theory and mathematical finance, helping us better grasp uncertainty in various scientific and economic fields. Ito’s contributions have had a lasting impact on how modern science and finance approach randomness and complex systems.
