#### Stability of Waves in Conservation Laws and Reaction-Diffusion Equations

###### Marta Lewicka (University of Chicago)

Abstract: Some fundamental laws of physics are stated as "conservation of X". In one space dimension, a general conservation law can be formulated mathematically as the vector partial differential equation u_t + f(u)_x = 0. In this talk, I will present an overview of the existence and qualitative theory of conservation laws, particularly focusing on my work about stability of large waves. Then I will touch upon recent work establishing a different kind of stability result for combustion waves in reaction-diffusion equations - these equations are not of conservation form.
