Yoshimura Lab
Machine-translated · View original
A lab that studies how things move, using mechanics and mathematics.
AboutAbout the lab
Reading the motion of nonlinear systems through mathematics.
The Yoshimura Lab uses mathematical equations to study how things move (dynamical systems).
It seeks to describe a wide range of phenomena, such as the motion of planets, fluid flow, and attitude control of robots, using geometry and mathematical ideas.
Incorporating experiments and numerical computation, the lab works to connect theory with real-world phenomena.
Key terms
- Dynamical system
- A mathematical description of how the position and motion of an object change over time
- Nonlinear system
- A mechanism or device in which the sizes of cause and effect are not proportional, so it behaves in complex ways
- Dirac structure
- A geometric framework that generalizes the symplectic structure, which is used to describe balance in mechanics

ResearchResearch themes
Building on a mathematical approach, the Yoshimura Lab studies the modeling of nonlinear systems and their dynamics and control. From the geometric theory of dynamical systems to complex fluid motion and spacecraft trajectory design, the lab works on theory, applications, and experiments.
*Illustrative imageDynamical Systems on Dirac Manifolds
The lab studies constrained dynamical systems within the geometric framework of "Dirac structures," which generalize symplectic structures. It also works on applications such as multibody systems.
*Illustrative imageStructure-Preserving Numerical Methods
The lab studies new numerical methods that preserve structures such as energy when computing conservative systems, such as the motion of planets and molecules.
*Illustrative imageGeometry of Nonequilibrium Thermodynamics
Extending ideas from Lagrangian mechanics, the lab studies how to describe nonequilibrium thermodynamic systems, which involve the flow of heat and entropy, in the language of geometry.
*Illustrative imageChaotic Flows in Convection
This research uses experimental apparatus to investigate how intricately tangled flows arise in "convection," which occurs when a temperature difference is applied to a thin layer of fluid.
