Green function is constructed for the boundary value problem under consideration and integral representation formula for the solution is found. Those results are applied to the pricing problems for a financial option of barrier type (two-asset barrier options with simultaneous barriers). At the end of the paper comparison principle for multi-asset Black-Scholes equations is proved.}, reviewer = {Ivan Landjev (Sofia)}, msc2010 = {62D05 (91B28 35Q80)}, identifier = {06102869}, }
