Query: Formal Fourier Jacobi Expansions and Special Cycles of Codimension 2   We prove that formal Fourier Jacobi expansions of degree 2 are Siegel modular
forms. As a corollary, we deduce modularity of the generating function of
special cycles of codimension 2, which were defined by Kudla. A second
application is the proof of termination of an algorithm to compute Fourier
expansions of arbitrary Siegel modular forms of degree 2. Combining both
results enables us to compute relations of special cycles in the second Chow
group.
