The equation under consideration belongs to the class of differential equations that arise, in particular, in the study of boundary value problems for differential equations containing a composition of left- and right-hand derivatives of fractional order, which, in turn, serve as the basis for modeling various physical and geophysical processes. In particular, such equations arise when describing dissipative oscillatory systems. In this work, the initial value problem in the unit interval is studied for the equation under consideration. A theorem for the existence and uniqueness of a solution to the problem under study is proven, and an explicit representation of the solution is constructed.</p></abstract><trans-abstract xml:lang="ru"><p>В работе рассматривается линейное обыкновенное дифференциальное уравнение с производной дробного порядка в смысле Герасимова–Капуто. Рассматриваемое уравнение относится к классу дифференциальных уравнений, возникающих, в частности, при исследовании краевых задач для дифференциальных уравнений, содержащих композицию лево- и правосторонних производных дробного порядка, которые, в свою очередь, выступают основой при моделировании различных физических и геофизических процессов. В частности, такие уравнения возникают при описании диссипативных колебательных систем. В работе для рассматриваемого уравнения исследуется начальная задача в единичном интервале. Доказана теорема существования и единственности решения исследуемой задачи, построено явное представление решения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>fractional order equation</kwd><kwd>Cauchy problem</kwd><kwd>Gerasimov–Caputo derivative</kwd><kwd>involution</kwd><kwd>fundamental solution</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>уравнение дробного порядка</kwd><kwd>задача Коши</kwd><kwd>производная Герасимова–Капуто</kwd><kwd>инволюция</kwd><kwd>фундаментальное решение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Нахушев А.
