Seminars for the week of March 28, 2011
Colloquium
Thursday, 3:30, in Vincent Hall 16Professor Jaigyoung Choe
of Korea Institute for Advanced Study
will speak on
"First eigenvalue of the Laplacian on a minimal surface in the 3-sphere" Abstract:A minimal surface is locally the surface with minimum
area. Therefore the Euclidean coordinates $x_1, x_2, x_3$ are harmonic on a minimal surface in $R^3$.
And the Euclidean coordinates $x_i (i = 1, 2, 3, 4)$ satisfy $\Delta x_i + 2x_i = 0$ on a minimal
surface in $S^3$ (as a subset of $R^4$). Then Yau conjectured that the first eigenvalue of the Laplacian
$\Delta$ on a compact embedded minimal surface in $S^3$ should be just 2. In this talk I will first show
how minimal surfaces are constructed in $S^3$, and give an easy proof of Yau's conjecture for most of the
minimal surfaces. (Joint work with M. Soret)
