Zhang, Shuguang Option pricing in an incomplete market with continuous asset price process. (English) Zbl 0903.90010 J. China Univ. Sci. Technol. 27, No. 3, 257-265 (1997). Summary: The problem of hedging contingent claims by portfolios constrained to take values in a given convex, closed subset of \({\mathcal R}^m\) in an incomplete market is studied. By extending the pair of portfolio and consumption to a triple of portfolio, extra-investment and consumption, an interval of arbitrage-free prices of a given contingent claim is obtained.
