For the interest of readers who do not need to deal with detailed mathematics, a succinct summary of the newly developed GSP N theory ( Chao, 2017 ) is given in this technical note. A streamlined presentation of the idea, concept, logic, formulation and the physics of the theory is given here such that the readers can more easily comprehend the overall picture and the explicit resulting equations to be used in implementation. The mathematical details are referred to the previous papers (Chao, 2016, 2017). All the relevant equations for the P 3 equivalent GSP 3 ( 3 ) theory are explicitly given. Issues of numerical implementation of the theory are discussed, and potentially viable methods are suggested and conceptually described. [ABSTRACT FROM AUTHOR]
