A softer connectivity principle
No full textWe give soft, quantitatively optimal extensions of the classical Sphere Theorem, Wilking’s connectivity principle and Frankel’s Theorem to the context of Rick curvature. The hypotheses are soft in the sense that they are satisfied on sets of metrics that are open in the C2-topologyThe first author was supported by research grants MTM2017-85934-C3-2-P from the MINECO and PID2021-124195NB-C32 from the AEI, and by ICMAT Severo Ochoa project SEV-2015-0554 (MINECO).

Focal radius, rigidity, and lower curvature bounds
No full text“This is the accepted version of the following article: Luis Guijarro and Frederick Wilhelm, Focal radius, rigidity, and lower curvature bounds, which has been published in final form at: https://doi.org/10.1112/plms.12113.”We prove a new comparison lemma for Jacobi fields that exploits Wilking's transverse Jacobi equation. In contrast to standard Riccati and Jacobi comparison theorems, there are situations when our technique can be applied after the first conjugate point.
Using it, we show that the focal radius of any submanifold N of positive dimension in a manifold M with sectional curvature greater than or equal to 1 does not exceed π 2 . In the case of equality, we show that N is totally geodesic in M and the universal cover of M is isometric to a sphere or a projective space with their standard metrics, provided that N is closed.
Our results also hold for k th intermediate Ricci curvature, provided that the submanifold has dimension ⩾ k . Thus, in a manifold with Ricci curvature ⩾ n − 1 , all hypersurfaces have focal radius ⩽ π 2 , and space forms are the only such manifolds where equality can occur, if the submanifold is closed.
Example 4.38 and Remark 5.4 show that our results cannot be proven using standard Riccati or Jacobi comparison techniquesThe first author was supported by research grants MTM2011‐22612, MTM2014‐57769‐3‐P, and MTM2017‐85934‐C3‐2‐P from the MINECO, and by ICMAT Severo Ochoa project SEV‐2015‐0554 (MINECO).

Frederick Brunner Collection 1711-1972 Bulk dates: 1930-1970
No full textThe Frederick Brunner Collection incorporates the research of the banker and LBI board chairman Frederick Brunner. Prominent subjects encompassed in this research include the Rothschild family and the history of Jews in Landau in der Pfalz. Some research on banking history and Jews as bankers may also be found here. The collection contains extensive newspaper clippings, articles, correspondence, notes, genealogical tables and family trees, and a few photographs.The following individuals and families are mentioned in this collection:Arendt, Hannah; Arnstein, Fanny; Brunner, Frederick; Brunner, Otto; Cohen family; Einstein, Berthold; Frank, Anne; Grünebaum, E; Guttmann, Bernhard; Heilbrunn, Rudolf; Heine, Salomon; Heinemann, Elkan; Israel, Wilfred; Israel, Wilfrid; Kauffmann, Felix; Landauer, Georg; Levison family; Maier, Hermann; Mendelssohn family; Merton, Richard; Merton, Wilhelm; Metzger, Kurt; Riesser, Jacob; Rothschild family; Rothschild, House of; Saalfeld, Martha, 1898-; Seligmann, Cäsar; Straus, Rahel; Sulzbach family; Susman, Margarete; Tietz family; Valentin, Veit; Warburg family.Friedrich Brunner was born in Landau in der Pfalz on December 11, 1895, the son of the salesman Albert Brunner and his wife. Friedrich Brunner was a banker and collector of Rothschildiana and material on the history of banking. He immigrated to the United States in March 1939 via England, and served as vice-chairman of Arnhold, S. Bleichroeder, Inc., in New York, and as chairman of the board of the Leo Baeck Institute. Frederick Brunner died in New Rochelle, New York, on July 19, 1974.22-page inventory.ProcessedProcesseddigitize
Wilhelm Sasnal’s Transitional Images
No full textIn her article the author offers a reframing of the discussion of how communities productively deal with their troubled pasts. The case in question is that of the post-war Polish national community, and its refusal to face so-called dark sides or shameful episodes of the historical past. The author concentrates on Wilhelm Sasnals’ artworks which deal with this gloomy heritage and reinterprets them in light of Donald W. Winnicott’s concept of transitional objects (as transitional images) thus pointing towards new possibilities in finding ways out of both discursive, political and pedagogical impasses in collective memory in Poland
Restrictions on submanifolds via focal radius bounds
No full textWe give an optimal estimate for the norm of any submanifold’s second fundamental form in terms of its focal radius and the lower sectional curvature bound of the ambient manifold.
This is a special case of a similar theorem for intermediate Ricci curvature, and leads to a C1,α compactness result for submanifolds, as well as a “soul-type” structure theorem for manifolds with nonnegative kth–intermediate Ricci curvature that have a closed submanifold with dimension ≥k and infinite focal radius.
To prove these results, we use a new comparison lemma for Jacobi fields from [18] that exploits Wilking’s transverse Jacobi equation. The new comparison lemma also yields new information about group actions, Riemannian submersions, and submetries, including generalizations to intermediate Ricci curvature of results of Chen and Grove. None of these results can be obtained with just classical Riccati comparison (see Subsection 3.1 for details.)The first author was supported by research grants MTM2011-22612, MTM2014-57769-3-P, and MTM2017-85934-C3-2-P from the MINECO, and by ICMAT Severo Ochoa project SEV-2015-0554 (MINECO).

Metric Deformations and Intermediate Ricci Curvature
No full textThis dissertation studies two topics in Riemannian geometry.First, we study the existence of totally geodesic submanifolds in Riemannian 3-manifolds. Murphy and Wilhelm showed that a generic closed Riemannian manifold has no totally geodesic submanifolds, provided the ambient space is at least four dimensional. We show that the set of metrics that admit totally geodesic submanifolds on a compact 3-manifold actually contains a set that is open and dense set in the Cq -topology, provided q ≥ 3.Second, we study the preservation of positive intermediate Ricci curvature under Riemannian submersions. Pro and Wilhelm showed that there are Riemannian submersions π : M → B with M a compact manifold with positive Ricci curvature, whose b-dimensional base has Ricci curvatures with both signs. We show that if Rick(M) > 0, then Rick(B) must be positive if k ∈ {1, 2, · · · , b − 1}, yet Ric(B) need not be positive if k = b

p. 106a “Rust nu zacht”: The composition and its composer could not be identified.
p. 114 “Aandoenlyks voor myn” is a contrafactum to Blüher’s “So ruhe frei von Kummer”, with the melody slightly modified.
Otto’s “Zingt bly” (p. 143) has not been found elsewhere.
Naumann’s “Du süßer Weinstock” (p. 120) appears a second time on p. 145.
