Welcome to Kôhei Sasaya's Homepage.

I am a postdoc (RIMS project fellow for "Stochastic Processes and Related Fields"). I specialize in analysis and related geometry on Fractals.
Keywords: fractal, quasisymmetry, Ahlfors regular conformal dimension, spectral dimension, resistance form, Dirichlet form.
