| - Juli Sergejewitsch Iljaschenko (russisch Юлий Сергеевич Ильяшенко, englische Transkription Yulij S. Ilyashenko; * 4. November 1943 in Moskau) ist ein russischer Mathematiker, der sich mit Dynamischen Systemen, Differentialgleichungen und Blätterungen im Komplexen befasst. Iljaschenko wurde 1969 bei Jewgeni Michailowitsch Landis an der Lomonossow-Universität promoviert. Er war Professor an der Lomonossow-Universität, war am Steklow-Institut und ist Professor an der Cornell University. Außerdem lehrte er an der Unabhängigen Universität Moskau. Er befasst sich unter anderem mit dem, was er als infinitesimales 16. Hilbert-Problem bezeichnet: was kann man über Anzahl und Lage der Grenzzyklen eines planaren polynomialen ebenen Vektorfeldes (das heißt Lösungen einer reellen polynomialen Differentialgleichung, Komponenten vom Grad n) machen? Das Problem ist ungelöst. Iljaschenko benutzte hier neue Techniken der komplexen Analysis (wie die Methode funktionaler Ko-Ketten, functional cochains). Er bewies das reelle ebene polynomiale Vektorfelder nur endlich viele Grenzzyklen haben. Unabhängig zeigte das auch Jean Écalle und ein älterer Beweisversuch von Henri Dulac (1923) wurde von Iljaschenko in den 1970er Jahren als fehlerhaft erkannt. Er war Invited Speaker auf dem Internationalen Mathematikerkongress 1990 in Kyoto (Finiteness Theorems for limit cycles). Er ist Fellow der American Mathematical Society. (de)

Ilyashenko was a professor at Moscow State University, an academic at Steklov Institute, and also taught at the Independent University of Moscow. He became a professor at Cornell University. His research deals with, among other things, what he calls the "infinitesimal Hilbert's sixteenth problem", which asks what one can say about the number and location of the boundary cycles of planar polynomial vector fields. The problem is not yet completely solved. Ilyashenko attacked the problem using new techniques of complex analysis (such as functional cochains). He proved that planar polynomial vector fields have only finitely many limit cycles. Jean Écalle independently proved the same result, and an earlier attempted proof by Henri Dulac (in 1923) was shown to be defective by Ilyashenko in the 1970s. He was an Invited Speaker of the ICM in 1978 at Helsinki and in 1990 with talk Finiteness theorems for limit cycles at Kyoto. In 2017 he was elected a Fellow of the American Mathematical Society.
