Financial markets play a prevailing role in the economy. The future legislation development in the field of globalfinance will unavoidably lead to friction to prevent speculative capital movements, always threatening with crisis. Thatis why we are interested in the financial market models with transaction costs.This thesis consists of three chapters. The first one establishes a criterion of absence of arbitrage opportunitiesgiving the existence of consistent price systems, i.e. martingale evolving in the dual cone expressed in physical units.The criterion holds for a family of financial market models in continuous time with small transaction costs.In the second chapter, we show the convergence of super-replication sets for a European option...
