am starting to make some basic notes on Gysin/Umkehr/pushforward maps in KK-theory, currently in fiber integration in the section In KK-theory. But still with some gaps.

added a bunch more commented reference here.

If anyone has further hnts to the literature on “KK-witnesses” of psuh-forward/Gysin/Umkehr maps in noncommutative topology/$C^\ast$-algebra theory, I’d be most thankful for pointers.
