On the mean-variance hedging problem

This paper proposes a new approach to the problem of the "optimal" control assets on an incomplete market. The approach develops the known mean-variance hedging method of Folmer, Sonderman, and Schweizer. Some technical assumptions on the approximating sequence such as the nondegeneracy condition and its elements belonging tu the space L-2 are excluded. We give examples and an interpretation of obtained results which connect them with such key financial-market notions as completeness and arbitrage.
