Quadratic Forms of Codimension 2 Over Finite Fields Containing F-4 and Artin-Schreier Type Curves
(Academic Press Inc Elsevier Science, 2012)
Let F-q be a finite field containing F-4. Let k >= 2 be an integer. We give a full classification of quadratic forms over F-q(k) of codimension 2 provided that certain three coefficients are from F-4. As an application of ...
Rings Whose Cyclic Modules Are Direct Sums Of Extending Modules
(Cambridge Univ Press, 2012)
Dedekind domains, Artinian serial rings and right uniserial rings share the following property: Every cyclic right module is a direct sum of uniform modules. We first prove the following improvement of the well-known ...
Rings Close to Semiregular
(Korean Mathematical Soc, 2012)
A ring R is called semiregular if R/J is regular and idempotents lift modulo J, where J denotes the Jacobson radical of R. We give some characterizations of rings R such that idempotents lift modulo J, and R/J satisfies ...
Complex And Symplectic Structures On Panelled Web 4-Manifolds
(Elsevier Science Bv, 2012)
We analyze the symplectic and complex structures on the panelled web 4-manifolds of S. Akbulut and M. Kalafat [1]. In particular, we give infinite families of examples of almost complex but not symplectic and not complex ...
A Note on Ads* Modules
(Springer Basel Ag, 2012)
We study the ADS* modules which are the dualizations of ADS modules studied by Alahmadi et al. ( J Algebra 352: 215-222, 2012). Mainly we prove that an amply supplemented module M is ADS* if and only if M-1 and M-2 are ...
On Almost Contractions In Partially Ordered Metric Spaces Via Implicit Relations
(Springeropen, 2012)
In this paper, we prove general fixed point theorems for self-maps of a partially ordered complete metric space which satisfy an implicit type relation. Our method relies on constructive arguments involving Picard type ...
Di-Uniformities and Hutton Uniformities
(Elsevier Science Bv, 2012)
The authors characterize di-uniformities on a texture (S, J) in the sense of Ozgag and Brown (Di-uniform texture spaces, Appl. Gen. Top. 4(1) (2003), 157-192) in terms of functions on the texturing J. This characterization ...
Global Attractor For The One Dimensional Wave Equation With Displacement Dependent Damping
(Pergamon-Elsevier Science Ltd, 2012)
We study the long-time behavior of solutions of the one dimensional wave equation with nonlinear damping coefficient. We prove that if the damping coefficient function is strictly positive near the origin then this equation ...
Polygon Morphing and Its Application in Orebody Modeling
(Hindawi Publishing Corporation, 2012)
Three different polygon morphing methods are examined. The first one is based on the utilization of the trimmed skeleton of the symmetric difference of the source and target polygons as an intermediate polygon. The second ...
