On the sign of solutions to some linear parabolic biharmonic equations
We study the sign of the solution of a linear parabolic biharmonic Cauchy problem in $\mathbb R^n$ by varying both the source and the initial datum. Eventual local positivity is proved under different assumptions and the problem of global positivity is discussed.
