The regularity of minimal surfaces in higher codimension
- Mathematics
- 2014
The Plateau’s problem investigates those surfaces of least area spanning a given contour. It is one of the most classical problems in the calculus of variations, it lies at the crossroad of several…
Lectures on chainlet geometry - new topological methods in geometric measure theory
- Mathematics
- 2005
These draft notes are from a graduate course given by the author in Berkeley during the spring semester of 2005. They cover the basic ideas of a new, geometric approach to geometric measure theory.…
Discrete methods in geometric measure theory
- Mathematics
- 2011
The thesis addresses problems from the field of geometric measure theory. It turns out that discrete methods can be used efficiently to solve these problems. Let us summarize the main results of the…
Differential geometry of generalized submanifolds
- Mathematics
- 2000
In the recent past a lot of authors have devoted systematic efforts to indagate problems related to compactness and degeneration phenomenons in classes of surfaces with integral bounds on curvature,…
Effective Fractal Dimension in Algorithmic Information Theory
- Mathematics
- 2008
Hausdorff dimension assigns a dimension value to each subset of an arbitrary metric space. In Euclidean space, this concept coincides with our intuition that smooth curves have dimension 1 and smooth…
Ravello lecture notes on geometric calculus -- Part I
- Mathematics
- 2005
In these notes of lectures at the 2004 Summer School of Mathematical Physics in Ravello, Italy, the author develops an approach to calculus in which more efficient choices of limits are taken at key…
Geometry and nonlinear analysis
- Mathematics
- 2002
Nonlinear analysis has played a prominent role in the recent developments in geometry and topology. The study of the Yang-Mills equation and its cousins gave rise to the Donaldson invariants and more…
CURVATURE MEASURES AND GENERALIZED MORSE THEORY
- Mathematics
- 2008
1.1. In studying the differential geometry of a hypersurface M in euclidean space E + 1 it has often proved fruitful to view the integral of the Gauss-Kronecker curvature (or "Gauss-Bonnet…
Lectures on the Geometric Group Theory
- Mathematics
- 2003
Preface The main goal of this book is to describe several tools of the quasi-isometric rigidity and to illustrate them by presenting (essentially self-contained) proofs of several fundamental…

In this paper we provide a complete classification of the local structure of singularities in a wide class of two-dimensional surfaces in R3 collected under the adjective (M, i, a) minimal by Almgren…
A NEW PROOF OF FEDERER’S STRUCTURE THEOREM FOR k-DIMENSIONAL SUBSETS OF R
- Mathematics
