My submission of my Connectors and Generalized Connectedness math article was rejected due a reviewer saying that the author (that is I) must go through the literature and find sources for general connectedness (e.g. Athangelskii+Wiegandt, Castellini, Herrlich, Petz, Preuss, Lowen, …..)
That is I was rejected due not enough references and links with existing literature about connectedness.
I quickly looked on some of these articles by the above mentioned authors which are freely available. I noted these use advanced category theory.
I confess that my knowledge of category theory is quite poor. I have bought the book MaсLane “Categories for the Working Mathematician” several months ago but haven’t yet took time to study it in details.
Sooner or later I will find time to study it. Afterward I hope to rewrite my article and submit it again. Now I consent that my article was rejected for a true reason and agree with the journal editor.
