Popis:	We present a necessary and sufficient conditions under which the sum of two EP elements in a *-ring has core inverse. As an application, we establish the conditions under which a block complex matrix with EP sub-blocks has core inverse. Comment: arXiv admin note: text overlap with arXiv:2209.10090
