As the title says, I am looking for a authoritative reference/monograph on this topic. My interest is in spectral properties of this PDE, and NOT on existence/uniqueness etc. which is usually the focus of most theoretical PDE texts. NOT on numerical methods to solve the PDE, which is usually the focus of engineering/physics PDE texts.

My motivation is to understand the various functional analytic aspects of this PDE under varying conditions: e.g. change in the spectrum when changing the advective component from something "regular" to chaotic, dependence of spectrum on bounded Vs unbounded flows, dependence on diffusivity etc.

I have been trying to read recent literature on such equations, and I haven't found a single solid source which has all the basic results on spectral properties of such equations.

Is there a recent book or monograph which focuses on spectral theory of (linear or nonlinear) parabolic PDEs in general, or advection-diffusion equations in particular ?

Thanks.

Your question is way too broad. Do you mean something like this: rd.springer.com/chapter/10.1007%2F978-3-0348-8545-4_10 or rd.springer.com/article/10.1007%2FBF01211592 ? –  András Bátkai Jul 31 '13 at 21:26
    
@Adras: I am looking for compilation of results similar to what you have linked to, but for advection-diffusion equations (ADE) (as applied in fluid mechanics). I guess there is whole lot more literature on Schrodinger's equation, than the "true" ADE with real coefficients. –  Piyush Grover Jul 31 '13 at 22:28
    
What do you mean by spectral properties? –  timur Aug 4 '13 at 0:21
    
@Timur: By spectral properties, I mean the various inferences that can be made about the spectrum of the advection-diffusion operator (i.e.L(f)= $u(x).\nabla f(x) + K\nabla^2 f(x) $) on the suitable function space such as $L^2(\Omega)$ where $\Omega\in R^n, x\in \Omega$, $u(x)$ is the advective velocity field. –  Piyush Grover Aug 4 '13 at 23:23

I am not sure whether there has been a comprehensive study of spectral properties of such equations, but you may be interested in the paper ``Diffusion and Mixing in Fluid Flow'' by Constantin, Kiselev, Ryzhik and Zlatos and the references therein.

Thanks for this reference. I haven't this one before, and it seems very few of the papers from the applied fluid mixing community have referred to it. –  Piyush Grover Aug 4 '13 at 23:29
    
After skimming through this paper, and spending some time tracking the references, I think I now have plenty of material on topic. Very helpful lead. –  Piyush Grover Aug 5 '13 at 21:15
