Applications of a first order differential subordination for analytic functions

Dziok J., Ohriska J.

Journal of Mathematics and Applications

2010

Vol. 32

39-46

In the paper, we define classes of analytic functions, in terms of subordination. By using Jack's Lemma and the Briot-Bouquet differential subordination we obtain some inclusion relations for defined classes.

Oscillation on the left and on the right

Ohriska J.

Scientific Issues of Jan Długosz University in Częstochowa. Mathematics

2009

Vol. 14

87-95

In the present paper we derive sufficient conditions for the linear differential equation (r(t)y′(t))′+p(t)y(t) = 0 to be either oscillatory or non-oscillatory on the left and eventually on the right. Some estimations of count of zero point s for solutions to considered equation on an interval are also presented.
