I work as a free lecturer and teach private students at schools and at advanced technical colleges.

My research interests include

Functional Analysis (Banach Lattices and Positive Operators, Strongly Continuous Semigroups)

Delay Differential Equations

Formal Languages

Computer Algebra

and a little

Number Theory (Strong Divisibility Sequences)

I am also interested in non-axiomatic foundations of mathematics and its applications to economics and evolution. This however seems to be more meta than mathematics and is thus off topic on this site.
