WORLDCOMP'10 Keynote Lecture - Prof. Yaroslav D. Sergeyev

Last modified 2010-06-22 18:19

The Infinity Computer and Numerical Computations with Infinite and Infinitesimal Numbers
Prof. Yaroslav D. Sergeyev
Father of the Infinity Computer
Distinguished Professor, University of Calabria, Rende (CS), Italy
Professor (part-time), N.I.Lobachevsky State University of Nizhni Novgorod, Russia

Date: July 13, 2010
Time: 06:00pm - 07:00pm
Location: Ballroom 1


    The lecture introduces a new methodology allowing one to execute numerical computations with finite, infinite, and infinitesimal numbers (see [1-11]) on a new type of a computer – the Infinity Computer (see the European Patent [2]). The new approach is based on the principle ‘The part is less than the whole’ introduced by Ancient Greeks that is applied to all numbers (finite, infinite, and infinitesimal) and to all sets and processes (finite and infinite). It is shown that it becomes possible to write down finite, infinite, and infinitesimal numbers by a finite number of symbols as particular cases of a unique framework different from that of the non-standard analysis.

    The new methodology (see survey [6]) evolves Cantor’s ideas in a more applied way and introduces new infinite numbers that possess both cardinal and ordinal properties as usual finite numbers. It gives the possibility to execute computations of a new type and simplifies fields of mathematics where the usage of the infinity and/or infinitesimals is necessary (e.g., divergent series, limits, derivatives, integrals, measure theory, probability theory, fractals, etc.). Numerous examples and applications are given. A number of results related to the First Hilbert Problem are established.

    In the following there are listed both operations that the Infinity Computer can execute and traditional computers are not able to perform and some of new areas of applications. The new approach allows:
      • to substitute symbols +∞ and -∞ by sets of positive and negative infinite numbers, to represent them in the memory of the Infinity Computer and to execute arithmetical operations with all of them numerically, as we are used to do with usual finite numbers on traditional computers;
      • to substitute qualitative descriptions of the type ‘a number tends to zero’ by precise infinitesimal numbers, to represent them in the memory of the Infinity Computer, and to execute arithmetical operations with them numerically as we are used to do with usual finite numbers using traditional computers;
      • to calculate divergent limits, series, and improper integrals, providing as results explicitly written different infinite numbers, to be possibly used in further calculations on the Infinity Computer;
      • to avoid appearance of indeterminate forms (e.g., in situations where it becomes necessary to calculate difference of two divergent series);
      • to evaluate functions and their derivatives at infinitesimal, finite, and infinite points (infinite and infinitesimal values of functions and their derivatives can be also explicitly calculated);
      • to study divergent processes at different infinite points;
      • to introduce notions of lengths, areas, and volumes of fractal objects obtained after infinite numbers of steps and compatible with traditional lengths, areas, and volumes of non-fractal objects and to calculate all of them in a unique framework.

      • Professor (part-time contract), N.I. Lobachevski Nizhni Novgorod State University, Nizhni Novgorod, Russia
      • Affiliated Researcher, Institute of High Performance Computing and Networking, Rende (CS), Italy
    Professor Yaroslav Sergeyev, Ph.D., D.Sc., has authored more than 150 research papers and 4 books in such fields as numerical analysis, parallel computations, number theory, fractals, etc. He has been awarded numerous prizes including the recent MAIK Prize for the best scientific monograph published in 2008 in Russian. In 2009 he has got the EU patent for a new revolutionary kind of computer - the Infinity Computer able to execute numerical computations with infinite, infinitesimal, and finite quantities. The last years he actively works in this new exciting research field. He serves as a member of editorial boards of three Springer journals. He has given numerous plenary and keynote lectures in prestigious international congresses. Numerous magazines, newspapers, and radio stations have dedicated a lot of space to his research.
