Exclude

Monodromy, the Riemann-Hilbert Problem, and the Differential Galois Groupat are meromorphic functions on .. We assume that the equation is regular at every point .∈.. Thus, for any point .∈., the equation has . independent solutions .,…, . consisting of vectors with coordinates in .({.?.}). It is known ([132], chap. 9; [225], p. 5) that these solutions converge in a disk

Differential Equations on the Complex Sphere and the Riemann-Hilbert Problemether with a map ?: .→. satisfying the rules: ?(.+.)=?(.)+?(.), and ?(.)=.+.?(.). In this definition, one refers to the chosen derivation of .. We want to introduce the more general concept of ., which avoids this choice. The advantage is that one can perform constructions, especially for the Rieman
