This year I had established some parametric inequalities on the parameters of a strongly regular graph like  in  Theorem V.1 of the publication :

Vasco Moço Mano, Luis  de Almeida Vieira, ''Some parametric inequalities on strongly regular graphs spectra'', International Journal of Pure Mathematics, vol 3, p-20-25.

And I had started   to write a book on Some techniques of integration of real functions that I pretend to finally in 2017-2 2018
