Starlikeness of sections of univalent functions
(Rocky Mountain Mathematics Consortium, 2014)
Let S be the class of all normalized analytic
and univalent functions in the unit disk D. In this paper, we
determine condition so that each section sn(f, z) of f ∈ S is
starlike in the disk |z| < rn. In particular, ...
Nonsingular acyclic matrices with full number of P-vertices
(Taylor & Francis Ltd, 2013)
We classify the trees for which there is a nonsingular matrix where each vertex is a P-vertex. In particular, we show that such trees have an even number of vertices. Both results provide answers to questions proposed by ...
