title = "Skew m-complex symmetric operators",
abstract = "In this paper we study skew m-complex symmetric operators. In particular, we show that if T ∈ L(H) is a skew m-complex symmetric operator with a conjugation C, then eitT, e−itT, and e−itT ∗ are (m, C)-isometric for every t ∈ R. Moreover, we examine some conditions for skew m-complex symmetric operators to be skew (m − 1)-complex symmetric.",
