Differential transform solution of some linear wave equations with mixed nonlinear boundary conditions and its blow up
(2010)Using Differential Transform to solve blow up solutions of some linear wave equation with mixed non-linear boundary conditions is proposed in this study.Non-linear boundary conditions cause the finite time blow up in ... -
The vibration and stability of non-homogeneous orthotropic conical shells with clamped edges subjected to uniform external pressures
(Elsevier, 2010)In this paper an analytical procedure is given to study the free vibration and stability characteristics of homogeneous and non-homogeneous orthotropic truncated and complete conical shells with clamped edges under uniform ... -
Conditions to be a forest for normalizer
(2010)In this paper, we examine some suborbital graphs for the normalizer of ?0(N) in PSL(2, R). -
Elliptic elements and circuits in suborbital graphs
(Hacettepe University, 2011)We consider the action of a permutation group on a set in the spirit of the theory of permutation groups, and graph arising from this action in hyperbolic geometric terms. In this paper, we examine some relations between ... -
A T-partial order obtained from T-norms
(2011)A partial order on a bounded lattice L is called t-order if it is defined by means of the t-norm on L. It is obtained that for a t-norm on a bounded lattice L the relation a ?T b iff a = T(x,b) for some x ? L is a partial ... -
Bidual of r-algebras
(Springer, 2011)We prove that the order continuous bidual of an Archimedean r-algebra is a Dedekind complete r-algebra with respect to the Arens multiplications. © 2010 Springer Science+Business Media, Inc. -
On suborbital graphs and related continued fractions
(Elsevier, 2011)In this paper, we study suborbital graphs for congruence subgroup ?0(n) of the modular group ? to have hyperbolic paths of minimal lengths. It turns out that these graphs give rise to a special continued fraction which is ... -
On conjugacy of elliptic elements and circuits in suborbital graphs of congruence subgroups
(2011)In this paper, we, for the first time, introduce the notion of conjugacy in suborbital graphs. Then we show that the conjugate elliptic elements of the modular group F and of congruence subgroups F 0(p) give rise to conjugate ... -
Circuit lengths of graphs for the Picard group
(Springer International Publishing Ag, 2013)In this paper, we examine some properties of suborbital graphs for the Picard group. We obtain edge and circuit conditions, then propose a conjecture for the graph to be forest. This paper is an extension of some results ... -
Connectedness of a suborbital graph for congruence subgroups
(Springer International Publishing Ag, 2013)In this paper, we give necessary and sufficient conditions for the graph to be connected and a forest. MSC: 20H10, 20H05, 05C05, 05C20. -
On the property of T-distributivity
(Springer International Publishing Ag, 2013)In this paper, we introduce the notion of T-distributivity for any t-norm on a bounded lattice. We determine a relation between the t-norms T and T', where T' is a T-distributive t-norm. Also, for an arbitrary t-norm T, ... -
Disconnectedness of the subgraph F-3 for the group Gamma(3)
(Springeropen, 2013)In this paper we show that the subgraph F-3 is disconnected and that for all integers m, we find all integers a and b such that (9m(2) - 4)a(2) + 4 and 5b(2) +/- 4 are square. It turns out that the set of numbers b comprises ... -
Eigenvalues and eigenfunctions of discontinuous two-point boundary value problems with an eigenparameter in the boundary condition
(Rocky Mt Math Consortium, 2013)In this paper we get asymptotic formulas for eigenvalues and eigenfunctions of discontinuous two-point boundary value problems with the eigenparameter in the boundary conditions with transmission conditions at the two ... -
Asymptotic formulations of the eigenvalues and eigenfunctions for a boundary value problem
(Wiley-Blackwell, 2013)In this work, a discontinuous boundary-value problem with retarded argument that contains a spectral parameter in the transmission conditions at the point of discontinuity is investigated. We obtained asymptotic formulas ... -
The arens triadjoints of some bilinear maps
(Univ Nis, Fac Sci Math, 2014)In this paper we study the Arens triadjoints of some bilinear maps on vector lattices. in particular, we prove that, for Archimedean vector lattices A and B, the Arens triadjoint i) T*** : A '' x A '' -> B '' of a positive ... -

(World Scientific Publ Co Pte Ltd, 2014)We determine formulae for the numbers of representations of a positive integer by certain octonary quadratic forms whose coefficients are 1, 2, 3 and 6. -
Ordering based on implications
(Elsevier Science Inc, 2014)Implication function I on a bounded lattice L is defined by means of some boundary conditions and monotonicity constraints. on the other hand, each implication function I on L defines a special relation which, in some ... -
Urinary incontinence in premenopausal women: prevalence, risk factors and impact on quality of life
(Wiley, 2014)ObjectivesTo determine the prevalence and risk factors of urinary incontinence (UI), and assess its impact on the quality of life (QOL) in premenopausal women. MethodsIn this cross-sectional study, 690 women aged from 18 ... -
Ordering based on implications (vol 276, pg 377, 2014)
(Elsevier Science Inc, 2014)In this paper, the study of ordering based on implications, given in (Information Sciences, 276 (2014) 377-386) is revised. the implication given in Example 1 is corrected and its right version is shown. (C) 2014 Elsevier ... -
Inverse problems for selfadjoint Schrodinger operators on the half line with compactly supported potentials
(Amer Inst Physics, 2015)For a selfadjoint Schrodinger operator on the half line with a real-valued, integrable, and compactly supported potential, it is investigated whether the boundary parameter at the origin and the potential can uniquely be ...
