Teodor Havârneanu

Teodor Havârneanu is a Professor at the Faculty of Mathematics, Alexandru Ioan Cuza University, Iași, Romania, a position he has held since 2008. He is also affiliated with the Institute of Mathematics of the Romanian Academy, Iași, where he has been a researcher since 2005. He previously served as Associate Professor (1995–2008) and Lecturer (1993–1995) at the same faculty. He was a visiting professor at the Department of Mathematics, University of Wyoming, USA, during the spring semesters of 2004 and 2005.

His educational background includes a degree in Mathematics from Alexandru Ioan Cuza University (1975–1979), followed by a specialization year in Functional Equations (1979–1980), and a PhD in 1991 with a thesis on viscous solutions for infinite-dimensional Hamilton-Jacobi equations, supervised by academician Viorel Barbu.

His research is centered on partial differential equations, particularly Hamilton-Jacobi equations, integro-differential equations with delay, and the controllability of fluid dynamics systems such as the Navier-Stokes and magnetohydrodynamic (MHD) equations. His work combines deep analytical methods with applications in control theory, especially in infinite-dimensional and nonlinear settings.

The analysis of his recent publications reveals a strong focus on exact controllability problems in fluid mechanics, with several joint papers on MHD and Navier-Stokes equations under various boundary conditions. His earlier work laid foundations in stability and semigroup theory for delay and neutral equations, evolving into sophisticated control-theoretic PDE analysis.

• Co-author of Controllability of Viscous Incompressible Fluid (Springer, forthcoming)
• Author of Ecuaţii integrale (Editura Alexandru Myller, 2007)

He has advised several researchers and co-authored significant papers with C. Popa, V. Barbu, and S.S. Sritharan. He has not received any explicitly mentioned scientific awards in the provided text. He is actively involved in research and continues to publish in high-impact journals in mathematical analysis and control theory.

He is associated with the Institute of Mathematics of the Romanian Academy and contributes to the academic life at Alexandru Ioan Cuza University through teaching and research leadership.
