We consider a boundary value problem for the beam equation, in which conditions mean that is embedded at one end and free other end. Some new estimates to positive solutions are obtained. sucien t existence of least solution established. An example given paper illustrate main results.
In this paper, the authors consider boundary value problem \begin{gather} \tag {E} x^{(2m)}(t)+(-1)^{m+1} f(x(t))=0, \quad 0<t<1, \\ {B} x^{(2i)}(0)=x^{(2i)}(1)=0, i=0,1,2,\cdots ,m-1, \end{gather} and give sufficient conditions for existence of any number symmetric positive solutions (E)â(B). The relationships between results in paper some recent work by Henderson Thompson (Proc. Amer. Math. Soc. 128 (2000), 2373â2379) are discussed.
In this paper, we consider the fourth order ordinary differential equation together with boundary conditions Some existence results for problem (E)—(B) are obtained. The here apply to more than just sublinear and superlinear cases discussed by most other authors.

We consider a nonlocal boundary value problem for third order differential equation. Sufficient conditions the existence and nonexistence of positive solutions are obtained. The results illustrated with some examples.
The authors consider booundary value problems for fourth order ordinary differential equations of the form with boundary conditions or They give sufficient (E)-(B1) and (E)-(B2) to have at least one positive solutions. also these no Examples illustrate that results are sharp included.
We use the reaction e+e−→μ+μ−, in Mark J detector at DESY high-energy e+e− collider PETRA, to test standard electroweak theory and find good agreement. also set limits on parameters of several extended gauge theories.Received 30 May 1985DOI:https://doi.org/10.1103/PhysRevLett.55.665©1985 American Physical Society

Using the Mark-J detector at high-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider PETRA, we compare data from hadron production with complete second-order QCD calculation over energy region 22 to 46.78 GeV. We determine parameter $\ensuremath{\Lambda}=100\ifmmode\pm\else\textpm\fi{}{30}_{\ensuremath{-}45}^{+60}$ MeV which yields strong-coupling constant ${\ensuremath{\alpha}}_{s}=0.12\ifmmode\pm\else\textpm\fi{}0.02$ for $\sqrt{s}=44$
The authors consider the boundary value problem $$ \begin{cases} u'''(t) = q(t)f(u), \quad 0 < t 1, \\ u(0) u'(p) u''(1) 0, \end{cases} $$ where $p \in(\frac{1}{2},1)$ is a constant. They give sufficient conditions for existence of multiple positive solutions to this problem. In so doing, they are able improve some recent results on Examples included illustrate results.
Abstract We study a class of nonlinear discrete fourth-order Lidstone boundary value problems with dependence on two parameters. The existence, uniqueness and positive solutions the parameters are discussed. Two sequences constructed so that they converge uniformly to unique solution problems. One example is included in paper. Numerical computations confirm our theoretical results. Recent results literature extended improved. Keywords: problemfourth-orderuniqueness dependencepositive...
