Yosef Yomdin
The Moshe Porath Professor of Mathematics
My area of research is analysis and
differential equations. I am trying to infer from the local structure of ordinary
and partial differential equations, the global structure of solutions. One direction
of the research is to use the local algebraic properties of the coefficients
of the ordinary differential equation to impose global restrictions (periodicity,
stability) on the motion, defined by this equation. Another direction of my
research is to use the local structure, together with a novel matching procedure,
in order to compute approximate solutions. The method has to do with the examination
of how complex some mathematical terms are. A similar approach helps in devising
methods for image compression.
