Let $g$ be the heat kernel. Are there constants $C_1, C_2>0$ such that $\frac{g(t_1, \cdot)}{t_1} \le C_1 \frac{g(C_2 t_2, \cdot)}{\sqrt{t_2}}$?

How to upper bound the difference between these two Gaussian-like densities?
Thank you so much for your help! I really appreciate that you take time to write such an elaborate answer.

@YemonChoi The existence of such sequence $(\lambda_n)$ is actually part of the assumption.

@IosifPinelis May I ask if you have any idea to derive the inequality?
