For a second order linear ordinary differential equation with a continual derivative, we construct a fundamental solution. By using the fundamental solution, we find the solution of the Cauchy problem for the considered equation. 相似文献

We study the Cauchy problem for an equation with singular Bessel operator. Unlike traditional methods to solve this problem, we apply Erde´ lyi–Kober fractional operator and find an explicit formula for the desired solution. We prove that the resulting formula is a unique classical solution to the problem. 相似文献

Zero-rank matrix numerical differentiation algorithms are applied to construct efficient numerical-analytical methods (so-called zero-rank matrix methods) to find the eigenvalues and eigenfunctions of boundary-value problems for second-order differential equations with a delayed argument. The proposed methods are analyzed.Translated from Vychislitel'naya i Prikladnaya Matematika, No. 58, pp. 19–24, 1986. 相似文献

On the basis of a generalized separation-of-variables method we propose an operator method of constructing the solution of
the Cauchy problem for a homogeneous system of partial differential equations of first order with respect to time and of infinite
order with respect to the spatial variables.

The concept of strongly positive operator is generalized and the properties of the introduced operators are analyzed. The
solutions of the Cauchy problem for a linear inhomogeneous differential equation with generalized strongly positive operator
coefficient are obtained. 相似文献

A sequence converging to the solution of the Cauchy problem for a singularly perturbed inhomogeneous second-order linear differential equation is constructed. This sequence is also asymptotic in the sense that the deviation (in the norm of the space of continuous functions) of its nth element from the solution of the problem is proportional to the (n + 1)th power of the perturbation parameter. A similar sequence is constructed for the case of an inhomogeneous first-order linear equation, on the example of which the application of such a sequence to the justification of the asymptotics obtained by the method of boundary functions is demonstrated. 相似文献
