This paper has used the Arbitrage Theorem (Gordan Theorem) to clarify some misconceptions in the literature of derivative pricing. First, unlike the claim of the irrelevancy of the underlying asset‘s (stock’s) expected return, it is found that the value of an option depends on the probability of the underlying asset (stock) rising or falling. Using the relationship between the relative price ratio between the two states:π/(1-π) and the probability of the up move, the paper also derives discrete-time versions of the Greeks. Second, since with no arbitrage, μ is a function of rf and σ, the Black-Scholes option pricing formula contains the underlying asset’s expected rate of return μ. Third, with a two-step contract, it has been shown that within a company, there is no first claim or seniority between bond and stock, but there is first claim among fixed-income assets (e.g., labor and bond), and labor is senior to bond.

Development of efficient solvers for solving linear systems Ax = b is one of the most significant issue on the field of computational science and engineering. The GMRES method of Saad and Schultz is a well-known solver as the typical Krylov subspace method for nonsymmetric linear systems. While the GMRES method show good convergence, it has difficulties in storage and computational costs. To remedy these difficulties, the restart technique is generally used as a practical choice. The restarted version of the GMRES method is called the GMRES(m) method. In this talk, we will focus on a relationship between the GMRES(m) method and the error equation and propose a new variant of the GMRES(m) method. Several numerical results will show that this new variant will be attractive.
