The origin,equivalent forms,and existing partial results concerning Hadwiger’s covering conjec-ture,which is a famous open problem that has lasted for nearly 60 years from convex and discrete geometry,are re-viewed. Related research problems and corresponding results are also presented. It is shown that,on the one hand,Hadwiger’s conjecture is still a very hard open problem,andon the other hand,there are a lot of fundamental re-searches to be done concerning this conjecture and problems related to it.
