In my ID card, my complete name has the following form : FirstName MiddleName1 MiddleName2 LastName. I will give an example (created name): Ahmed El Mustafa Ali. As you can see there is a space between El and Mustafa. Also, El is not in reality a middle name since it does not make sense if we take it alone (but Mustafa or ElMustafa are meaningful). In this example, I would like to shorten it A.E. Ali instead of A.E.M. Ali
Could I use only the initial letters of my FirstName, MiddleName1 and LastName in my short author name and skip that of MiddleName2 whereas in my complete name I do it correctly as the ID card?
