A New Special Function and Its Application in Probability
Zeraoulia Rafik, Alvaro H Salas, David L Ocampo
In this note we present a new special function that behaves like the error function and we provide an approximated accurate closed form for its CDF in terms of both Chebyshev polyn…

In this paper we prove the correctness of Dijkstra's algorithm. We also discuss it and at the end we show an application.
Exact solutions for the general fifth order KdV equation by the extended tanh method
Alvaro Salas, Cesar A. Gomez S., Jose Gonzalo Escobar Lugo
In this paper we show some exact solutions for the general fifth order KdV equation. These solutions are obtained by the extended tanh method.
About the seventh-order Kaup-Kupershmidt equation and its solutions
Alvaro Salas, Jairo Ernesto Castillo Hernandez, Jose Gonzalo Escobar Lugo
In this letter we obtain exact soliton and periodic solutions to the seventh-order Kaup-Kupershmidt equation. We make use of the Cole-Hopf transformation and two particular rationa…
