Research Interests
I have done work that can be considered complex analysis, number theory,
and algebraic geometry. I am especially interested in connections
between rational solutions and functional solutions to systems of
algebraic equations. For instance, consider the equation of the unit circle,
x2+y2=1. This equation has many
rational solutions, such as (3/5)2+(4/5)2=1,
coming from Pythagorean triples. The unit circle equation also has the
"functional solution" (sin t)2+(cos t)2=1.
On the other hand, if n>3,
then xn+yn=1
has only a few rational solutions (this is
Fermat's Last Theorem/Weil's Theorem or the
Mordell Conjecture/Faltings Theorem, depending on what one means by
"few" and "rational"). Similarly,
xn+yn=1 has no
non-constant "entire function" solutions -- this follows easily from,
for instance, the Uniformization theorem. One area I often work in is
a field called "p-adic" analysis. Working with functions of p-adic numbers
is sort of halfway in between algebra and analysis, so the idea is it might
help us understand how functional solutions are related to rational solutions.
Another area I work in is Nevanlinna theory, which extends the Fundamental
Theorem of Algebra to meromorphic functions. Finally, I have research
interests in classical complex analysis, particularly using geometric methods
to better understand various inequalities.
