Using the modified CK's direct method, we derive a symmetry group theorem of (2+1)-dimemsional Broer-Kaup-Kupershmidt (BKK) system. Some exact solutions of the model are given by the simple method.
In this article, numerical computations applying the finite-difference time-domain (FDTD) method are performed. Lightning electromagnetic fields radiated by a lightning strike to the Gaisberg Tower in ...
