  Rolf Nevanlinna - Wikipedia, the free encyclopedia
Rolf Herman Nevanlinna (October 22, 1895, Joensuu - May 28, 1980, Helsinki) is perhaps the most famous Finnish mathematician.
He was particularly appreciated for his work in theory of functions (i.e., complex analysis).
His opinions in politics were sometimes somewhat controversial, but his talents as an amateur musician were widely appreciated.

Nevanlinna was offered Weyl's chair when he left Zurich but refused.
The main results of Nevanlinna theory appeared in a 100 page paper in 1925.
Since 1982, an award, the Rolf Nevanlinna Prize, is presented at the International Congress of Mathematicians.

The Rolf Nevanlinna Prize Committee is chosen by the Executive Committee of the International Mathematical Union.
The Rolf Nevanlinna Prize in mathematical aspects of information science was established by the Executive Committee of the International Mathematical Union (IMU) in April 1981.
The prize was named the Rolf Nevanlinna Prize in honor of Rolf Nevanlinna (1895-1980), who had been Rector of the University of Helsinki and President of the IMU and who in the 1950s had taken the initiative to the computer organization at Finnish universities.

 On Nevanlinna's Secondary Deficiency (ResearchIndex)
Analogies between the Nevanlinna theory and the theory of heights in number theory have motivated to the determination the precise error term of the second fundamental theorem of the Nevanlinna theory.
The Nevanlinna secondary deficiency, introduced by P.M. Wong, gives the error term in a certain sense.
We first prove that, from a topological point of view, almost all meromorphic functions have secondary deficiency negative infinity and that the set of meromorphic functions having maximum...

A Nevanlinna--Pick Approach to Time-Domain Constrained i Control: SIAM Journal on Control and Optimization Vol.
In this paper, generalized Nevanlinna--Pick theory is used to solve a time-domain constrained $i$ control problem for linear time-invariant discrete-time systems.
First it is shown that if constraints are imposed only over a finite horizon (i.e., only on the first $n$ samples), then the problem reduces to a finite-dimensional convex minimization problem.

It also shows that the new conjecture is implied by the earlier conjecture.
As with most of the author's conjectures, this new conjecture stems from analogies with Nevanlinna theory; in this case it corresponds to a Second Main Theorem in Nevanlinna theory with truncated counting functions.
The original abc conjecture of Masser and Oesterlé corresponds to the Second Main Theorem with truncated counting functions on
