-EXTENSION OF A GENERALIZATION OF GOTTLIEB POLYNOMIALS IN TWO VARIABLES
Choi, Junesang ;
Journal of the Chungcheong Mathematical Society , volume 25, issue 2, 2012, Pages 253~265
DOI : 10.14403/jcms.2012.25.2.253
Abstract
Gottlieb polynomials were introduced and investigated in 1938, and then have been cited in several articles. Very recently Khan and Akhlaq introduced and investigated Gottlieb polynomials in two and three variables to give their generating functions. Subse- quently, Khan and Asif investigated the generating functions for the
-analogue of Gottlieb polynomials. Also, by modifying Khan and Akhlaq's method, Choi presented a generalization of the Gottlieb polynomials in
variables to give two generating functions of the generalized Gottlieb polynomials
. Here, we aim at defining a
-extension of the generalized two variable Gottlieb polynomials
and presenting their several generating functions.

LOCAL CONVERGENCE RESULTS FOR NEWTON'S METHOD
Argyros, Ioannis K. ; Hilout, Said ;
Journal of the Chungcheong Mathematical Society , volume 25, issue 2, 2012, Pages 267~275
DOI : 10.14403/jcms.2012.25.2.267
Abstract
We present new results for the local convergence of Newton's method to a unique solution of an equation in a Banach space setting. Under a flexible gamma-type condition [12], [13], we extend the applicability of Newton's method by enlarging the radius and decreasing the ratio of convergence. The results can compare favorably to other ones using Newton-Kantorovich and Lipschitz conditions [3]-[7], [9]-[13]. Numerical examples are also provided.

INFINITE SERIES RELATION FROM A MODULAR TRANSFORMATION FORMULA FOR THE GENERALIZED EISENSTEIN SERIES
Lim, Sung-Geun ;
Journal of the Chungcheong Mathematical Society , volume 25, issue 2, 2012, Pages 299~312
DOI : 10.14403/jcms.2012.25.2.299
Abstract
In 1970s, B. C. Berndt proved a transformation formula for a large class of functions that includes the classical Dedekind eta function. From this formula, he evaluated several classes of infinite series and found a lot of interesting infinite series identities. In this paper, using his formula, we find new infinite series identities.

Abstract
The power inequality
holds for the points

Abstract
For a norm 1 function
in the Fourier-Stieltjes algebra of a locally compact group we define the space of
-harmonic operators in the non-commutative
-space associated to the group von Neumann algebra of G. We will investigate some properties of the space and will obtain a precise description of it.

HARMONIC MAPS BETWEEN THE GROUP OF AUTOMORPHISMS OF THE QUATERNION ALGEBRA
Kim, Pu-Young ; Park, Joon-Sik ; Pyo, Yong-Soo ;
Journal of the Chungcheong Mathematical Society , volume 25, issue 2, 2012, Pages 331~339
DOI : 10.14403/jcms.2012.25.2.331
Abstract
In this paper, let Q be the real quaternion algebra which consists of all quaternionic numbers, and let G be the Lie group of all automorphisms of the algebra Q. Assume that g is an arbitrary given left invariant Riemannian metric on the Lie group G. Then, we obtain a necessary and sufficient condition for an automorphism of the group G to be harmonic.

DOI : 10.14403/jcms.2012.25.2.341
Abstract
The Reidemeister orbit set plays a crucial role in the Nielsen type theory of periodic orbits, much as the Reidemeister set does in Nielsen fixed point theory. Extending our work on Reidemeister orbit sets, we improve our theorem for formulae for Nielsen type essential orbit numbers.

The purpose of this paper is to provide some corrections regarding algebraic flaws encountered in the paper entitled "Sixteenth-order method for nonlinear equations" which was published in January of 2010 by Li et al.[9].

A FAST LAGRANGE METHOD FOR LARGE-SCALE IMAGE RESTORATION PROBLEMS WITH REFLECTIVE BOUNDARY CONDITION
Oh, SeYoung ; Kwon, SunJoo ;
Journal of the Chungcheong Mathematical Society , volume 25, issue 2, 2012, Pages 367~377
DOI : 10.14403/jcms.2012.25.2.367
Abstract
The goal of the image restoration is to find a good approximation of the original image for the degraded image, the blurring matrix, and the statistics of the noise vector given. Fast truncated Lagrange (FTL) method has been proposed by G. Landi as a image restoration method for large-scale ill-conditioned BTTB linear systems([3]). We implemented FTL method for the image restoration problem with reflective boundary condition which gives better reconstructions of the unknown, the true image.
