A Stronger Reflection Principle for Temperature Functions
Soon‐Yeong Chung · Journal of the London Mathematical Society · 2000
A reflection principle is given for temperature functions on a rectangle in the plane with much weaker conditions than the classical continuity to zero at the boundary, which improves a continuous version of Widder. As an application of this result a uniqueness theorem is given for solutions of the Cauchy problem of the heat equation on a semi-infinite rod.
