Rev. Howard J. Kenna, C.S.C., Memorial Professor of Mathematics
An internationally recognized leader in metric differential geometry, Karsten Grove has profoundly influenced the development of modern Riemann geometry. His findings on the non-linear center of mass and critical point theory for distance functions, for example, are now considered basic tools in comparison geometry. His “Grove Program,” moreover, which is used to classify positively curved manifolds by their symmetry group, has become a flourishing research area.
Crossing the boundaries of mathematical subjects, Grove has also made fundamental contributions in a variety of other areas, including geodesics, rational homotopy theory in geometry, singular metric foliations, and manifolds with curvature bounded from below.
A native of Denmark, Grove joined the Notre Dame faculty in 2007, and has presented his work all over the globe. He is and has been editor for a number of journals including Acta Mathematica, one of the world’s oldest and most prestigious mathematics journals.
The four Kenna Professorships were created by the University to memorialize Father Howard Kenna (’26), a Fellow and Trustee of Notre Dame. In 1955, he was appointed president of the University of Portland, a position he held until becoming the provincial superior of the Indiana Province of the Congregation of Holy Cross in 1962.
