Mátyás A. Sustik
I hold a Master's degree in Mathematics from the Eötvös Loránd Science University in Budapest (1996).
I have been working as a Software engineer for IBM in Austin since May, 1998.

Research Interests

Primarily numerical linear algebra and scientific computing:
  • Theory of frames.   (A special overcomplete set of vectors.)
  • Eigenvalue problems for structured matrices, algorithm efficiency, stability.
I am also interested in automated software and hardware verification and theorem proving.


Diagram for the Kurschak problemI proposed the following geometry problem which appeared on the 2004 Kürschák József Mathematical Competition for Hungarian High School Students:


Let ABC an arbitrary triangle.  There is unique circle (that we denote by k on the diagram) in the BAC angle region to which AB and AC are tangential in some P and Q points, and which touches the circumcirle of ABC from outside.  Prove that the F midpoint of PQ is the center of a circle touching all sides of ABC!
