Disconjugacy of Second-order Linear Differential Equations with Non- Negative Coefficients
His basic criterion for disconjugacy turned out to be 1 0 is continuous and fal/P= °°, then the substitution t — fll/p transforms the first equation into one where p = l and the new f-interval is infinite. Thus this more general case reduces to Nehari's and again the criterion is 1 <X(o). However part of the whole picture seems to be lost by this transformation. If Ial...
متن کاملOn the stability of linear differential equations of second order
The aim of this paper is to investigate the Hyers-Ulam stability of the linear differential equation$$y''(x)+alpha y'(x)+beta y(x)=f(x)$$in general case, where $yin C^2[a,b],$ $fin C[a,b]$ and $-infty
متن کاملOn the Hyper-order of Solutions of Second Order Linear Differential Equations with Meromorphic Coefficients
In this paper, we investigate the growth of solutions of the linear differential equation 0 = Bf f A f , where ) (z A and 0) )( ( z B are meromorphic functions. More specifically, we estimate the lower bounded of hyperorder of solutions of the equation with respect to the conditions of ) (z A and 0) )( ( z B if solutions 0 ( f ) of the equation is of infinite order. keywords: ...
متن کاملNonoscillatory Solutions of Second Order Differential Equations with Integrable Coefficients
The asymptotic behavior of nonoscillatory solutions of the equation x" + a{t)\x\' sgnx = 0, y > 0 , is discussed under the condition that A(t) = limr_00/, a(s)ds exists and A(t) > 0 for all t. For the sublinear case of 0 < y < 1 , the existence of at least one nonoscillatory solution is completely characterized.
متن کاملSecond order linear differential equations with generalized trapezoidal intuitionistic Fuzzy boundary value
In this paper the solution of a second order linear differential equations with intuitionistic fuzzy boundary value is described. It is discussed for two different cases: coefficient is positive crisp number and coefficient is negative crisp number. Here fuzzy numbers are taken as generalized trapezoidal intutionistic fuzzy numbers (GTrIFNs). Further a numerical example is illustrated.
