Sufficient Conditions for Janowski Starlikeness [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
Let A,B,D,E∈[−1,1] and let p(z) be an analytic function defined on the open unit disk, p(0)=1. Conditions on A, B, D, and E are determined so that 1+βzp'(z) being subordinated to (1+Dz)/(1+Ez) implies that p(z) is subordinated to (1+Az)/(1+Bz).

The lower bounds for the rank of matrices and some sufficient conditions for nonsingular matrices [PDF]

open access: yesJournal of Inequalities and Applications, 2017
The paper mainly discusses the lower bounds for the rank of matrices and sufficient conditions for nonsingular matrices. We first present a new estimation for ∑ i = 1 n | λ i | 2 $\sum_{i=1}^{n} \vert \lambda_{i} \vert ^{2}$ ( λ i $\lambda_{i}$ is an ...

New Sufficient Conditions for Hamiltonian Paths [PDF]

open access: yesThe Scientific World Journal, 2014
A Hamiltonian path in a graph is a path involving all the vertices of the graph. In this paper, we revisit the famous Hamiltonian path problem and present new sufficient conditions for the existence of a Hamiltonian path in a graph.
