"Now a little trivial heuresis is in order."
— The late Waclaw Szymanski on p. 279 of
"Decompositions of operator-valued functions
in Hilbert spaces" (Studia Mathematica 50.3
(1974): 265-280.)
See "A Talisman for Finkelstein," from midnight
on the reported date of Szymanski's death. That post
refers to "the correspondence in the previous post
between Figures A and B" … as does this post.
