New sufficient conditions for starlike and convex functions
(Işık University Press, 2014)Let A be the class of analytic functions f(z) in the open unit disc. Applying the subordination, some sufficient conditions for starlikeness and convexity are discussed. -
Free surface flow over a triangular depression
(Işık University Press, 2014)Two-dimensional steady free-surface flows over an obstacle is considered. The fluid is assumed to be inviscid, incompressible and the flow is irrotational. Both gravity and surface tension are included in the dynamic ... -
