Fourth-Order Differential Equations with Integer Indices of Fuchs
2001, vol. 6, no. 4, pp. 449-453
We study the differential equations of fourth order, in the polynomial class. We give the list of equations of this type, whose the indices of Fuchs are integers, then equations who can be with fixed critical points.
