iron, cobalt and copper are metals, which appear together in many real samples, both natural and artificial. recently a classical univariate micellar colorimetric method has been developed for determination of these metal ions. the organized molecular assemblies such as micelles are used in spectroscopic measurements due to their possible effects on the systems of interest. the ability of micel...

in this paper, the exp-function method, with the aid of a symbolic computation system such as maple, is applied to the (2+1) -dimensional calogero bogoyavlanskii schiff equation. exact and explicit generalized solitary solutions are obtained in more general forms. the free parameters can be determined by initial or boundary conditions. the method is straightforward and concise, and its applicat...
