My public lecture given in the Serbian Academy of Sciences and Arts under the title "Generalized functions, Equations, Microlocal Analysis" was consisted of two parts. The first part was devoted to the explanations of generalized function and microlocal theory within the theory of PDE, while the second part is related to the presentation of results which I have obtained in collaboration with my colleagues, J. Toft, J. Vindas, N. Teofanov, K. Johansson and D. Rakic. Here I will recall the extended version of the second part of my talk.
