Some generalized difference statistically convergent sequence spaces in 2-normed space

Başarır, Metin; Konca, Şükran (SPRINGEROPEN, 2013)

In this paper, we define a new generalized difference matrix Bn(m) and introduce some Bn(m)-difference statistically convergent sequence spaces in a real linear 2-normed space. We also investigate some topological properties ...
On Complex Fibonacci Quaternions

Halıcı, Serpil (SPRINGER BASEL AG, 2013)

Horadam defined the Fibonacci quaternions and established a few relations for the Fibonacci quaternions. In this paper, we investigate the complex Fibonacci quaternions and give the generating function and Binet formula ...
ON THE DIOPHANTINE EQUATION x(2)-kxy+y(2)+2(n)=0

Keskin, Refik; Karaatlı, Olcay (UNIV MISKOLC INST MATH, 2012)

In this paper, we determine when the equation in the title has an infinite number of positive integer solutions x and y when 0 <= n <= 10. Moreover, we give all the positive integer solutions of the same equation for 0 <= n <= 10.
ON SOME COMMON FIXED POINT THEOREMS WITH RATIONAL EXPRESSIONS ON CONE METRIC SPACES OVER A BANACH ALGEBRA

Öztürk, Mahpeyker; Başarır, Metin (HACETTEPE UNIV, FAC SCI, 2012)

In the present paper we have defined a new space called a BA-cone metric space by taking a Banach algebra instead of a Banach space. Some common fixed point theorems involving rational expressions have been proved and some ...
On compact operators on the Riesz B-m-difference sequence space

Başarır, Metin (SPRINGER INTERNATIONAL PUBLISHING AG, 2012)

In this paper, we give the characterization of some classes of compact operators given by matrices on the normed sequence space r(p)(q) (B-m), which is a special case or the paranormed Riesz B-m-difference sequence space ...
The stress field problem for a pre-stressed plate-strip with finite length under the action of arbitrary time-harmonic forces

Eröz, Mustafa (ELSEVIER SCIENCE INC, 2012)

In the framework of the three-dimensional linearized theory of elastodynamics the finite element modeling of the stress field problem for the pre-stressed plate-strip with finite length resting on a rigid foundation under ...
Active control of a smart beam with time delay by Legendre wavelets

Yılmaz, Yalçın (ELSEVIER SCIENCE INC, 2012)

Active vibration control in a flexible beam is investigated by taking into account the time-delay which may occur in voltage controlled piezoelectric actuators. The voltage applied to a piezoelectric patch actuator to ...
On Fibonacci Quaternions

Halıcı, Serpil (BIRKHAUSER VERLAG AG, 2012)

In this paper, we investigate the Fibonacci and Lucas quaternions. We give the generating functions and Binet formulas for these quaternions. Moreover, we derive some sums formulas for them.
Asymptotic behaviour of the solutions of inverse problems for pseudo-parabolic equations

Yaman, Metin; Gözükızıl, Ömer Faruk (ELSEVIER SCIENCE INC, 2004)

We study asymptotic proximity as t --> infinity of the Solutions of the inverse problem for a pseudo-parabolic equation with an unknown source function. The overdetermination condition is given in integral form. (C) 2003 ...
On Some Lacunary Almost Convergent Double Sequence Spaces and Banach Limits

Başarır, Metin; Konca, Şükran (HINDAWI PUBLISHING CORPORATION, 2012)

The object of this paper is to introduce some new sequence spaces related with the concept of lacunary strong almost convergence for double sequences and also to characterize these spaces through sublinear functionals that ...
QUANTUM CODES FROM CODES OVER GAUSSIAN INTEGERS WITH RESPECT TO THE MANNHEIM METRIC

Güzeltepe, Murat (RINTON PRESS, INC, 2012)

In this paper, some nonbinary quantum codes using classical codes over Gaussian integers are obtained. Also, some of our quantum codes are better than or comparable with those known before, (for instance [[8, 2, 5]](4+i)).
Some identities deriving from the nth power of a special matrix

Halıcı, Serpil (SPRINGER INTERNATIONAL PUBLISHING AG, 2012)

In this paper, we consider the Horadam sequence and some summation formulas involving the terms of the Horadam sequence. We derive combinatorial identities by using the trace, the determinant and the nth power of a special matrix.
PARABOLIC CLASS NUMBER OF A SUBGROUP OF THE NORMALIZER OF Gamma(0)(m)

Keskin, Refik (UNIV MISKOLC INST MATH, 2012)

In this study, we introduce a subgroup of the normalizer of Gamma(0)(m) and we calculate parabolic class number of this group.
