The following discussion is an archived debate of the proposed deletion of the article below. Please do not modify it. Subsequent comments should be made on the appropriate discussion page (such as the article's talk page or in a deletion review). No further edits should be made to this page.

The result was delete. Consensus is clearly against keeping. Whether a redirect makes sense is not clear from this discussion, but remains up to interested expert editors. Sandstein 10:43, 18 May 2022 (UTC)[reply]

The concept is not notable, and the definition given in the first line is almost nonsensical: in general, the coefficients of the differential equations that are considered are analytic, and the solutions are also analytic, which means that their natural domain is a large part of the complex plane, even if everything is real in the equation.

Except for the first line, the article consists only of assertions that are dubious, unsourced or unrelated to the article title (generally, at least two of these three issues).

So, nothing is to be salvaged, and there is no plausible redirect for this non existing concept. D.Lazard (talk) 10:40, 10 May 2022 (UTC)[reply]

I'm wondering if a redirect to complex analysis would make sense. If a student has just learned a little about differential equations, gets curious about if there's a complex-number version of what they've seen, and Googles "complex differential equation", that's probably where they should end up.

The content of the article I expect from the title of the article was like Hörmander's method for several complex variables. I also expect that Cauchy-Riemann and harmonic analysis related to PDEs would be explained. Also, I think this page is strongly related to complex differential forms and Dolbeault cohomology (De Rham cohomology) etc. So , TNT.--SilverMatsu (talk) 16:16, 11 May 2022 (UTC)[reply]
Redirect to Monodromy#Differential equations in the complex domain for the time being. That page is a better target than complex analysis as ODEs are not mentioned there. I think this is a topic worthy of an article and that the current version at least includes a collection of links to specific topics in the field. However as it is currently written it may be too informal so keeping it might be counter-productive, and unfortunately I don't have the time or expertise to edit it at this point. jraimbau (talk) 13:14, 14 May 2022 (UTC)[reply]
