comment boundedness of a sequence $ \in L^{\infty}(I,H^1(M))\cap Lip(I,L^2(M))$ implies that its temporal derivative is bounded as well
Because that is the same as Lip.

comment Zeros of Polynomial with decreasing coefficients
$x^3+x+1$ is a counterexample.

comment Zeros of Polynomial with decreasing coefficients
The answer is still no. Before posting such "conjectures," why not try a few simple cases first? I am emphatically voting to close.

comment $L^2$ bound on solution of PDE in terms of $L^2$ norm of initial value
Yes, and much more than this is known. Try a literature search with keywords "Dirichlet problem" and "L2 data."

Try the keyword "interpolation spaces." You will find your references.

comment Upper bound for a ratio of modified Bessel functions
It looks like any "simple" upper bound would yield the exact location of the zeros of $I_\nu$. What exactly do you expect?

comment Laplacian on non-compact domains
I think you want $1-\Delta$ rather than $1+\Delta$.

comment Fractional Laplacian on the torus
Fourier series are your friend. But this is hardly a research level question.

How did this arise? It looks and quacks a lot like homework.
