Bi-univalent properties for certain class of Bazilevič functions defined by convolution and with bounded boundary rotation

In this paper, we obtain bi-univalent properties for certain class of Bazilevič functions defined by convolution and with bounded boundary rotation. We will find coefficient bounds for |a₂| and |a₃| for the class...

Balanced factor congruences of double MS-algebras

In this paper, we introduce the concepts of Stone elements, central elements and Birkhoof central elements of a double MS-algebra and study their related properties. We observe that the center C(L) of a double MS

Generalized Jordan triple derivations associated with Hochschild 2–cocycles of rings

In the present work, we introduce the notion of a generalized Jordan triple derivation associated with a Hochschild 2–cocycle, and we prove results which imply under some conditions that every generalized Jord...
