::Thank you very much for teaching me. Thanks for giving me many interesting examples of other manifolds. Sure, it seems too narrow, so I turn the suggestion into a section redirect to the ___domain of holomorphism. Then, I will modify the lead sentence and correct it to say, "One of the reasons why this field has come to be studied is that the boundary does not become a natural boundary." thanks!--[[User:SilverMatsu|SilverMatsu]] ([[User talk:SilverMatsu|talk]]) 08:01, 23 December 2020 (UTC)
::Withdraw from merge the ___domain of holomorphy. I might suggest merging conditions that are equivalent to the ___domain of holomorphy, but I thought that should be considered on the ___domain of holomorphy. Writing the ___domain of holomorphy on this page has no effect on withdrawal. thanks!--[[User:SilverMatsu|SilverMatsu]] ([[User talk:SilverMatsu|talk]]) 13:53, 26 December 2020 (UTC)
 
== Unclear sentence ==
 
In the section '''Radius of convergence of power series''', this sentence:
 
"''In the power series <math>\sum_{k_1,\dots,k_n=0}^\infty c_{k_1,\dots,k_n}(z_1-a_1)^{k_1}\cdots(z_n-a_n)^{k_n}\ </math>, it is possible to define ''n'' combination of <math>r_\nu</math><ref group=note>This combination may not be unique.</ref>
 
:"''<math>\begin{cases}
\text{Absolutely converge on}\ \{ z=(z_1, z_2, \dots, z_n) \in {\Complex}^n \mid | z_\nu - a_\nu | < r_\nu, \text{ for all } \nu = 1,\dots,n \}\\
\text{Does not absolutely converge on}\ \{ z=(z_1, z_2, \dots, z_n) \in {\Complex}^n \mid | z_\nu - a_\nu | > r_\nu, \text{ for all } \nu = 1,\dots,n \}
\end{cases}</math>
''"
 
is very poorly worded and makes no sense in normal English. I hope someone knowledgeable about this subject who is also familiar with English can rewrite this so that it is readable and accurate.
 
I'm '''guessing''' that what is '''meant''' is this:
 
... it is possible to define ''n'' positive real numbers <math>r_\nu</math> such that the power series
 
<math>\begin{cases}
\text{is absolutely convergent on}\ \{ z=(z_1, z_2, \dots, z_n) \in {\Complex}^n \mid | z_\nu - a_\nu | < r_\nu, \text{ for all } \nu = 1,\dots,n \}\\
\text{and is not absolutely convergent on}\ \{ z=(z_1, z_2, \dots, z_n) \in {\Complex}^n \mid | z_\nu - a_\nu | > r_\nu, \text{ for all } \nu = 1,\dots,n \}
\end{cases}</math>
 
(Is that right?) This would read better if we could get rid of the "cases" curly bracket and just use normal English here.[[Special:Contributions/128.120.234.237|128.120.234.237]] ([[User talk:128.120.234.237|talk]]) 06:09, 29 December 2020 (UTC)

== Proposed merge of [[Several complex variables]] into [[Complex analysis]] ==
 
Properly belongs as one article, functions of one complex variable are a special case of functions of several complex variables and both should be discussed in the same article with complex analysis. Furthermore, [[complex variables]] is an unacceptable and confusing DAB page which should also redirect here. If those articles need a DAB, it can be accomplished with a hat note and a link to a new [[complex variables (disambiguation)]]. Size is not an issue.

:{{Ping|Footlessmouse}} Nice to me you. I'm in support of inserting Several complex variables into the complex analysis page, but please wait a bit for page consolidation.In complex analysis, holomorphic is a characteristic property, which is different from several real variables.In other words, we need to write about the differences from several real variables.In order to clarify the difference from complex analysis, it may be possible to integrate several pages included in [[:Category:Several complex variables]], or to have duplicate contents.--[[User:SilverMatsu|SilverMatsu]] ([[User talk:SilverMatsu|talk]]) 13:11, 1 November 2020 (UTC)
