Drinfeld–Sokolov–Satsuma–Hirota (DSSH) equation approximation solution is acquired by using the
residual power series method (RPSM) in this study. The conformable sense is used to characterize the
fractional derivatives ...
In this paper, Dirac notations are operated to find the Hamiltonian matrix with the eigenvector
basis for two and three-state cases, and its tensor product version with a change of basis.
