This generalises work of Brown and Gilbert for the case of crossed modules of groups, and part of this is needed for work on 2-dimensional holonomy to be developed elsewhere.eninfo:eu-repo/semantics/closedAccesscrossed modulesgroupoidsautomorphismsactors2-crossed modulesHomotopies and automorphisms of crossed modules of groupoidsArticle11218520610.1023/A:10235443036122-s2.0-0037674019Q2WOS:000182478100007Q4
