The model of the considered system is described by partial differential equations. The players (opponents) control parameters occur on the right-hand side of the equation and are subjected to various constraints. The first player’s goal is to bring the system from one state into another desired state;the second player’s goal is to prevent this from happening. We represent new sufficient conditions for bringing the system from one state into another. The finite-difference method is used to solve this problem.展开更多

Personal weakness of the protagonist: his effort to evade his past functions as the last straw leading to his invisibility. Therefore, this paper tries to analyze the cause of the invisibility of the protagonist by further textual analysis in an attempt to reveal how a nameless African American reflects the existential crisis of modern man.展开更多
