Fourier method for a quasilinear parabolic equation with periodic boundary condition
(Hacettepe University, 2008)A multidimensional mixed problem with Neuman type periodic boundary condition is studied for the quasilinear parabolic equation ?u/?t-a2 ?2u/?x2 = f(t, x, u). The existence, uniqueness and also continuity of the weak ... -
Lattice operations of positive bilinear mappings
(Mathematical Society of the Rep. of China, 2008)In this paper we establish extension theorems for additive mappings ? : A+ ×B+ ? C+, where A, B are Riesz spaces (lattice ordered spaces or vector lattices) and C is an order complete Riesz space, to the whole of A×B, ... -

Family of surface with a common null geodesic
(2009)We analyzed the problem of finding a surfaces family through a null curve with Cartan frame. We constructed a differential equation system such that a given null curve is an isogeodesic curve on a surface. In addition, ... -
Solution of a mixed problem with periodic boundary condition for a Quasi-linear Euler-Bernoulli equation
(Hacettepe University, 2010)In this paper, the existence and uniqueness of the weak generalized solution of a mixed problem with periodic boundary condition for a quasi-linear Euler-Bernoulli equation are examined, and an estimation of the differences ... -
Suborbital graphs for a special subgroup of the normalizer of Γ0 (m)
(Shiraz University, 2010)In this paper, we find the number of sides of circuits in suborbital graph for the normalizer of ?0(m) in PSL(2,R), where m will be of the form 2p2, p is a prime and p ?1 (mod 4). In addition, we give a number theoretical ... -
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 ... -
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 ... -

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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -

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, ... -
