Welcome to the Department of Mathematics

Department of Mathematics at Illinois State University

Dr. Lucian Ionescu

Professor
  • BIOGRAPHY
  • With a thorough expertise in computer science and software design, my research is application-oriented in mathematical-physics. I teach at Il. St.U, was visiting professor at Wesleyan U. and several times visitor at the Institute des Hautes Etudes Scientifique, Paris, France.
  • CURRENT COURSES
  • MAT 120.Sec 002 Finite Mathematics
  • MAT 400.Sec 002 Independent Study
  • TEACHING INTERESTS
  • Topology and differential geometry, abstract algebra, calculus, quantum computing, differential equations, number theory ...
  • RESEARCH INTERESTS
  • Applications of mathematics (homological algebra methods and deformation theory) to quantum physics and quantum computing ... it's just a different kind of Calculus, where discrete changes are modeled as processes: Quantum Information Dynamics. An example desk-top application? Quantum Optics! (For more info see My Books ) My current research, as of 2010 or so, is in Number Theory as the Ultimate Physics Theory.
