Abstract Stereographic projection has been used in Rock Engineering for decades to represent rock mass discontinuities graphical form and carry out further stability analysis. Currently, there are computer programs available this purpose. The objective of technical note is present some closed expressions related stereographic projections such as the prediction a possible joint set. These soluti...

This research work is dedicated to solving the n-generalized Korteweg–de Vries (KdV) equation in a fractional sense. The method combination of Sumudu transform and Adomian decomposition method. has significant advantages for differential equations that are both linear nonlinear. It easy find solutions fractional-order PDEs with less computing labor.
