Zeros of the Jimbo, Miwa, Ueno tau function
We introduce a family of local deformations for meromorphic connections on P1 in the neighborhood of a higher rank (simple) singularity. Following the scheme in Malgrange [Mathematique et Physique, Progress in Mathematics (Birkhäuser, Boston, 1983), Vol. 37, pp. 381–400, ibid., pp. 401–426; ibid., pp. 427–438] we use these local models …
