Solution: Infinitesimal Generators and Kolmogorov Equations: Conceptual Boundary
Solution
The clean case satisfies the definition stated in the lesson. The failure case breaks one of the hypotheses, such as adaptedness, convexity, definiteness, smoothness, or constraint qualification. Naming the broken hypothesis is the answer.
Takeaways
- Most errors come from using the right formula outside its domain.
- The failed assumption is usually more informative than the final number.
- Finance models need hypotheses because prices and risks are otherwise not well-defined.
