AboutAbout the lab
Studying differential equations on symmetric spaces
The Kakehi Lab studies differential equations and integral geometry on symmetric spaces.
The lab has papers and talks on snapshot problems for the wave equation and the Klein-Gordon equation.
The lab belongs to the Analysis Group of the Degree Program in Mathematics.
Key terms
- differential equation
- An equation that expresses relationships among the rates of change of quantities that vary from moment to moment.
- symmetric space
- A geometric space, including the sphere, that has a symmetric structure around each point.
- integral geometry
- A field that studies the properties of a space by integrating over collections of objects in it, such as lines and planes.
- surjectivity
- The property that every function in the target space is obtained as a result of applying the operator.
ResearchResearch themes
