Richard Schoen – Mathematics
Rolf Schock Prizes 2017 Photo: Private Photo: Richard Schoen Richard Schoen – Mathematics The Rolf Schock Prize in Mathematics 2017 is awarded to Richard Schoen, University of California, Irvine and Stanford University, USA, “for groundbreaking work in differential geometry and geometric analysis including the proof of the Yamabe conjecture, the positive mass conjecture, and the differentiable sphere theorem”. Richard Schoen holds professorships at University of California, Irvine and Stanford University, and is one of three vice-presidents of the American Mathematical Society. Schoen works in the field of geometric analysis. He is in fact together with Shing-Tung Yau one of the founders of the subject. Geometric analysis can be described as the study of geometry using non-linear partial differential equations. The developments in and around this field has transformed large parts of mathematics in striking ways. Examples include, gauge theory in 4-manifold topology, Floer homology and Gromov-Witten theory, and Ricci-and mean curvature flows. From the very beginning Schoen has produced very strong results in the area. His work is characterized by powerful technical strength and a clear vision of geometric relevance, as demonstrated by him being involved in the early stages of areas that later witnessed breakthroughs. Examples are his work with Uhlenbeck related to gauge theory and his work with Simon and Yau, and with Yau on estimates for minimal surfaces. Schoen has also established a number of well-known and classical results including the following: • The positive mass conjecture in general relativity: the ADM mass, which measures the deviation of the metric tensor from the imposed flat metric at infinity is non-negative. -

Stable Minimal Hypersurfaces in Four-Dimensions
STABLE MINIMAL HYPERSURFACES IN R4 OTIS CHODOSH AND CHAO LI Abstract. We prove that a complete, two-sided, stable minimal immersed hyper- surface in R4 is flat. 1. Introduction A complete, two-sided, immersed minimal hypersurface M n → Rn+1 is stable if 2 2 2 |AM | f ≤ |∇f| (1) ZM ZM ∞ for any f ∈ C0 (M). We prove here the following result. Theorem 1. A complete, connected, two-sided, stable minimal immersion M 3 → R4 is a flat R3 ⊂ R4. This resolves a well-known conjecture of Schoen (cf. [14, Conjecture 2.12]). The corresponding result for M 2 → R3 was proven by Fischer-Colbrie–Schoen, do Carmo– Peng, and Pogorelov [21, 18, 36] in 1979. Theorem 1 (and higher dimensional analogues) has been established under natural cubic volume growth assumptions by Schoen– Simon–Yau [37] (see also [45, 40]). Furthermore, in the special case that M n ⊂ Rn+1 is a minimal graph (implying (1) and volume growth bounds) flatness of M is known as the Bernstein problem, see [22, 17, 3, 45, 6]. Several authors have studied Theorem 1 under some extra hypothesis, see e.g., [41, 8, 5, 44, 11, 32, 30, 35, 48]. We also note here some recent papers [7, 19] concerning stability in related contexts. It is well-known (cf. [50, Lecture 3]) that a result along the lines of Theorem 1 yields curvature estimates for minimal hypersurfaces in R4. Theorem 2. There exists C < ∞ such that if M 3 → R4 is a two-sided, stable minimal arXiv:2108.11462v2 [math.DG] 2 Sep 2021 immersion, then |AM (p)|dM (p,∂M) ≤ C. -
A Representation Formula for the P-Energy of Metric Space Valued
A REPRESENTATION FORMULA FOR THE p-ENERGY OF METRIC SPACE VALUED SOBOLEV MAPS PHILIPPE LOGARITSCH AND EMANUELE SPADARO Abstract. We give an explicit representation formula for the p-energy of Sobolev maps with values in a metric space as defined by Korevaar and Schoen (Comm. Anal. Geom. 1 (1993), no. 3-4, 561–659). The formula is written in terms of the Lipschitz compositions introduced by Ambrosio (Ann. Scuola Norm. Sup. Pisa Cl. Sci. (4) 3 (1990), n. 17, 439–478), thus further relating the two different definitions considered in the literature. 0. Introduction In this short note we show an explicit representation formula for the p-energy of weakly differentiable maps with values in a separable complete metric space, thus giving a contribution to the equivalence between different theories considered in the literature. Since the early 90’s, weakly differentiable functions with values in singular spaces have been extensively studied in connection with several questions in mathematical physics and geometry (see, for instance, [1, 2, 3, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22]). Among the different approaches which have been proposed, we recall here the ones by Korevaar and Schoen [15] and Jost [12] based on two different expressions of approximate energies; that by Ambrosio [1] and Reshetnyak [18] using the compositions with Lipschitz functions; the Newtonian–Sobolev spaces [11]; and the Cheeger-type Sobolev spaces [17]. As explained by Chiron [3], all these notions coincide when the domain of def- inition is an open subset of Rn (or a Riemannian manifold) and the target is a complete separable metric space X (contributions to the proof of these equiva- lences have been given in [3, 11, 19, 22]). -
