摘要:

研究了具有常系数分数阶微分算子Dzhrbashyan-Nersesyan的线性常微分方程组的初值问题。证明了所研究的边值问题解的存在唯一性定理。的解决方案是明确的Mittag-Leffler函数的矩阵参数。Dzhrbashyan-Nersesyan算子是Riemann-Liouville、Caputo和Miller-Ross分数阶微分算子的推广。所得结果作为特例包含了与Riemann-Liouville、Caputo和Miller-Ross导数的常微分方程组初值问题研究有关的结果,所研究的初值问题是它们的推广

英文摘要:

The paper investigates the initial problem for a linear system of ordinary differential equations with the fractional differentiation operator Dzhrbashyan -- Nersesyan with constant coefficients. The existence and uniqueness theorems of the solution of the boundary value problem under study are proved. The solution is constructed explicitly in terms of the Mittag-Leffler function of the matrix argument. The Dzhrbashyan -- Nersesyan operator is a generalization of the Riemann -- Liouville, Caputo and Miller-Ross fractional differentiation operators. The obtained results as special cases contain results related to the study of initial problems for systems of ordinary differential equations with Riemann -- Liouville, Caputo and Miller -- Ross derivativess, and the investigated initial problem generalizes them
