Smooth solutions to the heat equation which are nowhere analytic in time
Xin Yang, Chulan Zeng, Qi S. Zhang
The existence of smooth but nowhere analytic functions is well-known (du Bois-Reymond, Math. Ann., 21(1):109-117, 1883). However, smooth solutions to the heat equation are usually…

Time analyticity of the biharmonic heat equation, the heat equation with potentials and some nonlinear heat equations
Chulan Zeng
In this paper, we investigate the pointwise time analyticity of three differential equations. They are the biharmonic heat equation, the heat equation with potentials and some nonl…
