Ulmer preprint

Ulmer preprint

[Steve Lack]

Dear Category Theorists,

I have seen a few references to a 1977 manuscript by Fritz Ulmer, entitled “Bialgebras in locally presentable categories”.
John Gray’s 1991 review of the Makkai-Pare book on accessible categories describes it as “never published”. 

If anyone has a copy of this, I’d be very interested to see it.

Regards,

Steve Lack.

Perhaps the preprint could be made more widely available if found?

Note that Ulmer's mathematics genealogy page is sorely incomplete!

His Dr phil. supervisor is 'unknown', but perhaps not to readers of this list.

I found the Ulmer manuscript "Bialgebras in locally presentable categories"  in my archives. It is a University of Wuppertal preprint, and it is rather  long, say 100 pages.
I am in the process of scanning it, and can, when finished, send copies on request.

In the preface, Ulmer says that "The incentive to study sub-bialgebras "generated" by a subobject resulted from a problem which was given to us (= a  group of students) in Heidelberg in 1964 by A. Dold."

This may shed some light on the genealogy question.
