Existence of an equilibrium with limited stock market participation and power utilities

Battle Count: 226

While primarily theoretical, the paper provides insights into market equilibrium under limited participation, which could inform trading strategies in markets with restricted access or heterogeneous investors.

The paper deals with complex mathematical proofs and singular ODEs, making practical implementation challenging. It's more relevant for theoretical understanding than direct application in trading systems.

The paper provides detailed mathematical proofs and theorems, which can be verified by other mathematicians. No computational experiments are involved.
