Final Report

a) Peer-reviewed

Peer-reviewed Publications

I pay a lot of attention to various strategies of dissemination of my scientific research results: Journals, Academic Networks, Web Site, Preprints, Conference Presentations and Posters.

(a.1)
Journals:
My modern tetralogy which provides the foundations of the present stand-alone project has been published in internationally well-known journals: Monatshefte für Mathematik (MOFM) by Springer, the International Journal of Number Theory (IJNT) by World Scientific Publishing, Singapore, and the Journal de Théorie des Nombres de Bordeaux (JTNB) by CEDRAM.

My recent trilogy which extends the scope of the present stand-alone project has been published in Special Issues on Group Theory and Number Theory of Advances in Pure Mathematics (APM) by Scientific Research Publishing (SciRP), Wuhan, China.

(a.2)
Academic Networks:
My publications can be identified uniquely by means of my ORCID identifier:
orcid.org/0000-0002-4258-6455

Important works of my entire academic carreer are listed at
ORCID,

and can be downloaded from
Research Gate,

Academia,

and, in particular, from the arXiv (Cornell University Library)
