In this paper, we establish and perfect the dualities among the Laplace transform (LT), Laplace-Carson transform (LCT), Sumudu transform (ST), and a novel integral transform (NIT). In addition, some novel properties of the NIT are explored and the NIT is applied to solve some partial differential equations (PDEs).

“…Chiarella and Ziogas (2005) overcome some problems with the Laplace transform using the Fourier one. Alternatively, Kang et al (2017) use the Laplace–Carlson transform. An approach based on deriving the limits for the boundaries by the use of capping is presented by Ma et al (2018).…”
The so-called American strangle options are examined in this paper. Their main characteristic is the combined put and call feature. The holder has the right to exercise prematurely choosing the option's style-put or call. We abandon the traditional assumption that the put strike is below the call one considering arbitrary values. We also assume that the put and call weights are different. The equations for the early exercise boundaries are derived in the perpetual case.After that we approximate numerically these boundaries for the finite maturity options maximizing the option holder's utility. On the basis of them we apply a Crank-Nicolson finite difference method to the corresponding Black-Scholesstyle partial differential equation to obtain the fair option price.
“…In recent years, many researchers have proposed exotic American style options with various approaches. Based on the Laplace-Carson Transform (LCT) approach, Park and Jeon [13] and Kang et al [14] obtained numerically the prices of American knock-out options with rebate and American strangle options, respectively. Zaevski [15] proposed a new form of the early exercise premium for the American type options using the technique of stopping times.…”

“…Wong and Lau [24] studied exotic path-dependent options and provided an efficient and accurate approach for valuing the options under the MRL model. Motivated by these works and the work of Kang et al [14], we consider the MRL model for the underlying asset as an extensional work for the American strangle option pricing. We used the partial differential equation (PDE) approach to present the pricing formula of the American strangle option under the MRL model explicitly.…”
This paper investigates the American strangle option in a mean-reversion environment. When the underlying asset follows a mean-reverting lognormal process, an analytic pricing formula for an American strangle option is explicitly provided. To present the pricing formula, we consider the partial differential equation (PDE) for American strangle options with two optimal stopping boundaries and use Mellin transform techniques to derive the integral equation representation formula arising from the PDE. A Monte Carlo simulation is used as a benchmark to validate the formula’s accuracy and efficiency. In addition, the numerical examples are provided to demonstrate the effects of the mean-reversion on option prices and the characteristics of options with respect to several significant parameters.
