Navarro conjectured that the $p$-blocks of a finite group all of whose height 0 characters have the same degree are exactly the nilpotent blocks defined by M. Brou\u00e9 and L. Puig. In this paper, we check that this conjecture holds for spin-blocks of the covering group $2.{\\mathfrak A}_n$ of the alternating group ${\\mathfrak A}_n$, thereby solving a case excluded from the study of quasi-simple groups by Malle and Navarro.<\/jats:p>","DOI":"10.37236\/704","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T22:39:44Z","timestamp":1578695984000},"source":"Crossref","is-referenced-by-count":2,"title":["On a Conjecture of G.
