Fixed point theorems on uniform spaces
(Indian Nat Sci Acad, 2003)Two general fixed point theorems for F: (X, U) --> (2(X), U*) are proved. Examples are given to illustrate the generality of the theorems. -
Fixed point of multivalued mapping in uniform spaces
(Indian Academy Sciences, 2003)In this paper we prove some new fixed point theorems for multivalued mappings on orbitally complete uniform spaces. -
On accelerated iterative methods for the solution of systems of linear equations
(Taylor & Francis Ltd, 2002)In literature, it has been reported that the convergence of some preconditioned stationary iterative methods using certain type upper triangular matrices as preconditioners are faster than the basic iterative methods. In ... -
A certain subclass of analytic functions involving operators of fractional calculus
(Pergamon-Elsevier Science Ltd, 1998)Making use of certain operators of fractional calculus, we introduce a new class T-mu(n,lambda,alpha) of functions which are analytic and univalent in the open unit disk U and obtain a necessary and sufficient condition ... -
Some families of multivalently analytic functions with negative coefficients
(Academic Press Inc Jnl-Comp Subscriptions, 1997)The authors introduce and study three novel subclasses of analytic and p-valent functions with negative coefficients. In addition to finding a necessary and sufficient condition for a function to belong to each of these ... -
Applications of q-calculus in operator theory
(Springer New York, 2013)The approximation of functions by linear positive operators is an important research topic in general mathematics and it also provides powerful tools to application areas such as computer-aided geometric design, numerical ... -

(2016)Bu araştırmanın amacı, matematik öğretmeni adaylarının türev kavramı ile ilgili anlamalarını ve bu kavramı anlama sürecinde karşılaştıkları zorlukları ortaya koymaktır. Bu çalışma kapsamında türev kavramının -temel ... -
Lorentzian circle as a Lie group and a C ∞ action on Lorentz spaces of two dimension
(1999)We define a product on Lorentz circle that is similar to Lorentzian inner product. This product is expanded to Lorents space of two dimension. So we have an C{\infty} action of Lorentz circle on Lorents space of two ... -
Some characterizations of rectifying curves in the Euclidean space E4
(2008)In this paper, we define a rectifying curve in the Euclidean 4-space as a curve whose position vector always lies in orthogonal complement N{\perp} of its principal normal vector field N. In particular, we study the ... -
Some inequalities on P-valently starlike and P-valently convex functions
(1999)In this paper, some inequalities on p-valently starlike functions and p-valently convex functions are given. Moreover, some consequences of the inequalities which are important for geometric function theory are also included. -
