Short Answer
Step by step solution
Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Regular Singular Point
- The coefficients of the lower-order terms have a power series expansion around \( x_0 \) that converges.
- The solution to the differential equation near \( x_0 \) can be expressed in a series form that converges.
Irregular Singular Point
- The coefficients of the equation do not have a convergent power series expansion about \( x_0 \).
- The solutions may not be representable in a convergent series form.
Differential Equation
Coefficient Convergence
- If coefficients converge to a power series in the neighborhood of the singular point, the point can be regular.
- If they diverge or do not form a series, it can be irregular.
