I am having a lot of fun in reading Visual Complex Functions by Professor Wegert. (It is a very interesting read and well-recommended by me.)
Inside it, he regularly lets things be and postpones until part 2 or book 2. I have asked Professor Wegert himself about his plans with it (or a title), but unfortunately he seems to be busy at the moment.
That's why I am asking the community: Does anyone know of the book 2 mentioned in Visual Complex Functions, or when it is due ?
In personal correspondence with the author back in 2018, he said that the plan still exists for a second volume, but he cannot say when it will appear.
I am looking forward to any news too. If I hear anything, I will try to remember to post an update here.
