It is about the demontration of the existence of operators’ calculations in domains with irregular and non-soft frontiers, through the use of the so-called Clifford Algebras, with potential application in frontier problems of Math-Phys.

The authors present more than 10 publications of the last 3 years about original results in specialized Magazines; 9 of them are very prestigious, such as Mathematical Methods in the Applied Sciences, published by John Wiley, (this publication is from 2002), two in Complex Variable and Clifford Algebra magazines and their applications in Math-Phys published by Birhauser, which is one of the most prestigious magazines in that sphere, another in Journal of Natural Geometry, English magazine and another in a very specific magazine of this sphere such as Advanced in Applied Clifford Algebras, which has an Editorial Committee of very high level, where the authors have published an extensive work of 11 pages.

Their most important publications are also registered in MathSciNet Bibliographic data, of American Mathematical Society, all with Copyright from 2003. They also have other articles that appeared in Mathematical Sciences Cuban Magazine of the University of Havana.

The authors have taken their important results to international events of that specialty: to the periodic Seminar on Clifford Analysis that takes place in the Gent University in Belgium, to the University of Shangai in China, to an event of computational Methods in Theory of functions in Portugal, and to international events of the Institute of Cybernetics, Mathematics and Physics (ICIMAF).
