comment Decidability of differential equations
If you are in a US university, and your library does not have it, use ILL service (interlibrary loan). If you are in other country, ask your librarian.

comment What is the Beltrami differential?
$(-1,1)$ form is a ratio of $(0,1)$ form and a $(1,0)$ form. The definition of Beltrami differential is similar to definition of any other differential. "To each local coordinate it puts a function into correspondence, which transforms in such and such way when we change the local coordinate".

comment Applications and main properties of hyperfunctions
I recommend to read Hormander, Analysis of Partial Differential Operators, vol. I, Ch. 9, where this is explained.

comment How should a mathematician approach the physics literature concerning percolation?
@Steve Huntsman: Some mathematicians find Cardy's arguments incomprehensible. It all depends on your background. But he stated one of the main conjectures in the subject, and even guessed the correct answer.
