Alexander Andrejewitsch Logunow (russisch ΠΠ»Π΅ΠΊΡΠ°Π½Π΄Ρ ΠΠ½Π΄ΡΠ΅Π΅Π²ΠΈΡ ΠΠΎΠ³ΡΠ½ΠΎΠ², englische Transkription Alexander Logunov; * 5. Dezember 1989 in Perm) ist ein russischer Mathematiker, der sich mit Harmonischer Analysis, Potentialtheorie und geometrischer Analysis befasst.
Logunow wurde 2015 an der UniversitΓ€t St. Petersburg bei Wiktor Chawin promoviert (Π Π³ΡΠ°Π½ΠΈΡΠ½ΡΡ
ΡΠ²ΠΎΠΉΡΡΠ²Π°Ρ
Π³Π°ΡΠΌΠΎΠ½ΠΈΡΠ΅ΡΠΊΠΈΡ
ΡΡΠ½ΠΊΡΠΈΠΉ, engl. On boundary properties of harmonic functions).cite-ref-1[1] Er ist am Tschebyschow-Mathematiklabor der UniversitΓ€t Sankt Petersburg und an der UniversitΓ€t Tel Aviv tΓ€tig.
Logunow erhielt 2017 den Clay Research Award mit Jewgenija Malinnikowa fΓΌr die EinfΓΌhrung neuartiger geometrisch-kombinatorischer Methoden zum Studium elliptischer Eigenwertprobleme.cite-ref-2[2] Er bewies unter anderem eine obere Schranke fΓΌr das Hausdorff-MaΓ der KnotenflΓ€che von Eigenfunktionen des Laplaceoperators auf kompakten glatten Mannigfaltigkeiten und untere Schranken (Vermutungen von Yau und Nadirashvili). FΓΌr 2018 erhielt er den Salem-Preis.cite-ref-3[3] FΓΌr 2020/21 erhielt er den EMS-Preis (Vortrag: Zero sets of Laplace eigenfunctions).cite-ref-4[4] FΓΌr 2021 erhielt er den New Horizons in Mathematics Prize fΓΌr neuartige Techniken zum Studium der LΓΆsungen elliptischer partieller Differentialgleichungen und ihre Anwendung auf lange ungelΓΆste Probleme der Geometrie von Knotenmengen.cite-ref-5[5]
