Method of Frobenius. >> and so is unramified at the prime 3; it is also irreducible mod 3. >> >> Section 8.4 The Frobenius Method 467 where the coefï¬cients a n are determined as in Case (a), and the coefï¬cients Î± n are found by substituting y(x) = y 2(x) into the differential equation. Regular and Irregular Singularities As seen in the preceding example, there are situations in which it is not possible to use Frobeniusâ method to obtain a series solution. The Frobenius method yields a basis of solutions. /FirstChar 33 Wall Paper 2. Can't Go There 6.
