Ritt second theorem

WebAn application of the second isomorphism theorem identifies projective linear groups: for example, the group on the complex projective line starts with setting = ⁡ (), the group of invertible 2 × 2 complex matrices, = ⁡ (), the subgroup of determinant 1 matrices, and the normal subgroup of scalar matrices = {():}, we have = {}, where is the identity matrix, and = ⁡ … WebJan 13, 2024 · There are already a few structure theorems on algebraic dependence in such differential fields. See e.g. [Epstein, Caviness 1979] and [Singer/Saunders/Caviness 1985]. But how can these structure theorems be applied to prove theorems for inverses in these differential fields, like Ritt's theorem, as Risch did it?
