Weband shows that fsoc(x) = (x2)1/2, fsoc(x) = [x]+ are strongly semismooth. Our proofs are based on an elegant relation between the vector-valued function fsoc and its matrix-valued counterpart (see Lemma 1). This relation enables us to apply the results from [6] for matrix-valued functions to the vector-valued function fsoc. Our proofs also use two WebWe show that the resolvent RA is a matrix-valued holomorphic function on ⇢(A) by ﬁnding power series expansions of RA at all points z 2 ⇢(A).
