Dear All,

I hope and pray you and your families are all well.

If I may, Isbell conjugacy
(https://conceptualmathematics.wordpress.com/2022/08/30/birkhoffs-theorem-from-a-geometric-perspective-a-simple-example/;
see p. 17 in http://tac.mta.ca/tac/reprints/articles/8/tr8.pdf; given
the current world situation, I thought it is good to have a copy of
important papers in multiple locations) is about a category of
contravariant functors and the dual category of a category of
covariant functors.

Is Isbell conjugacy implicit in CO- and CONTRA-VARIANCE and DUALIZATION?

Pardon me if this is silly.

I eagerly look forward to your corrections and clarifications.

Happy Daughters' Day :-)

Thanking you,
posina
