About me
I'm a PhD student in Ben-Gurion University of the Negev. My supervisor is Professor Eran Treister. I study numerical solvers for the Helmholtz equations: preconditioning approaches featuring multigrid methods and saddle-point systems.
אני רחלי יובל, סטודנטית לדוקטורט באוניברסיטת בן-גוריון בנגב. המנחה שלי הוא פרופסור ערן טרייסטר. אני חוקרת פותרנים נומריים למשוואות הלמהולץ: שיטות פרקונדישנינג מבוססות רב-סריג ומערכות נקודת-אוכף.
