The international Congress "ULTRAMATH" aims to present recent results in the whole spectrum of mathematics which are grounded on the use of ultrafilters and ultraproducts. Its main goals:

  • Disseminate information about the various techniques related to the use of ultrafilters and ultraproducts, and their potential to attack open problems.
  • Bring together researchers with different backgrounds, and encourage their collaborations and interactions, especially on topics connecting different areas of mathematics.

The covered topics include (but are not limited to):

  1. Additive/Combinatorial Number Theory.
  2. Combinatorics, Ramsey Theory, Ergodic Theory.
  3. Algebra.
  4. Geometry.
  5. General Topology.
  6. Measure Theory.
  7. Metric Spaces.
  8. Functional Analysis.
  9. Nonstandard methods.
  10. Set theory and foundations.

Greater prominence will be given to those results that satisfy (most of) the following conditions:

  • the results can be formulated and presented in non-specialist terms, and be in principle understandable by any practicing mathematician.
  • the usage of ultrafilters/ultraproducts is important (or even essential) in obtaining these results.
  • the results connect different areas of mathematics.
  • the results reveal new facets of known important topics.
