Abstract
Let R be a unital ring with involution. The pseudo core inverses of
differences and products of two projections are investigated in R. Some
equivalent conditions are obtained. As applications, the pseudo core
invertibility of the commutator pq - qp and the anti-commutator pq + qp are
characterized, where p; q are projections in R.
