I found this easy way to make contributions: just take some old results from the hard disk and dump them here. So, here is another 400+ pages of articles my me:
https://www.researchgate.net/publication/341099787_A_selection_of_book_chapters_and_conference_papers_from_1993_to_2010
Kind of old stuff. I do not think many will read these. Besides, I still have some 700+ pages that I yet have not put to the ResearchGate. I guess I will not put all of this text to there. Would have to scan much of it. Nobody would read it. It was only that the ResearchGate application complained that I should upload full texts. So, there they have some, let them be happy. I have still a lot more if they are not happy yet. But there is this advantage that at the moment I can easily make a new post without inventing anything new.
