Subject: Old question of McLarty on triposes
Date: Wed, 27 May 2020 22:01:35 +0930 [thread overview]
Message-ID: <E1jeIjp-00005g-JB@rr.mta.ca> (raw)
Dear all,
way back in 1998 Colin McLarty raised the following question:
>Can the adjoint lifting theorem for triposes (from Andy Pitts's dissertation)
>be gracefully transported to regular categories (presumably
>with some supplemental conditions)? If so, the theory of
>realizability toposes could be radically simplified,
>among other things (see Japp van Oosten's dissertation).
has there been any progress on or toward this in the last 22 years?
Best regards,
David
