What does negligation mean? Negligence?

Context:

the paper "Folgerungen aus den Capillaritätserscheinungen" (Conclusions Drawn from the Phenomena of Capillarity) from the year 1901 is a common product of Einstein & Marity;
in 3 of the 4 famous 1905 Annalen papers Mileva’s substantial role is probable, but in the "Electrodynamics of Moving Bodies" any substantial role of Marity is unfounded;
in later years Einstein’s memory was inconstant about roles of early coworkers, so the lack of mentions of Marity in various autobiographies does not indicate anything at all; and
the divorce left very bad memories in Einstein, so his negligation of the first wife as a colleague is psychologically understandable, although not so from the viewpoint of Physics.[42]
