Research Abstract

We have demonstrated the importance of boundary geometry of various Riemannian metrics when the boundary components act as facets where simplices meet within a simplicial complex, in terms of its effect on the global geometric structures of the simplicial complex. This has been observed and investigated in the contexts of Weil-Petersson geometry of Teichmuller spaces, singular minimal surface theory arising in Geometric Measure Theory, and the geometry of event horizons within Einstein manifolds.
