Asking this question as someone with a graduate student level understanding of smooth differential/Riemannian geometry (May be a bit more that Riemannian Geometry by Do Carmo). I am trying to upgrade my knowledge to the real-analytic set up.
Also my target is not to go in the direction of complex algebraic geometry (like Griffiths-Harris). I am primarily interested in building "analytic diffeomorphisms" and "analytic flows" on abstract analytic manifolds. I am interested in some basic materials which will eventually lead me in that direction.
Another question I asked, that may be more precise: What are some general strategies to build measure preserving real-analytic diffeomorphisms?
Till someone who actually knows something gets here, I will try to summarize some haphazard information I was collected:
Some articles (non survey styles) which might be useful:
(1) From a differentiable to a real analytic perturbation theory, applications to the Kupka Smale theorems - H.W. Broer and F.M. Tangerman.
(2) A non-stabilizable jet of a singularity of a vector field; the analytic case. In Algebraic aand Differential Topology - Global Differential Geometry - F. Takens (There is some kind of analytic partition of unity described here, where do you find this paper?)
(3) New Banach space properties of the disc algebra and $H^\infty$ - J. Bourgain (Also some kind of partition of unity discussed here, too hard to read)
I will keep searching and will add as I find for information.
