On the Adams-Riemann-Roch theorem in positive characteristic. [With an appendix by B. Koeck: Another formula for the Bott element]
No full textWe give a new proof of the Adams-Riemann-Roch theorem for a smooth projective morphism X ? Y, in the situation where Y is a scheme of characteristic p > 0, which is of finite type over a noetherian ring and carries an ample line bundle. This theorem implies the Hirzebruch-Riemann-Roch theorem in characteristic 0. We also answer a question of B. Koeck.[Appendix: The object of the appendix is to give another formula for the Bott element of a smooth morphism. This formula is analogous to a formula in the main part of the paper and extends a list of miraculous analogies explained in an earlier paper.

Family caregiver strain and resident distress in the dementia population of nursing home facilities
No full textEnd-of-life care in the U.S. is increasingly provided in nursing homes (NHs), and over half of all NH residents have some degree of cognitive impairment. Given the prevalence of this cognitive decline, there is a surprising gap in research related to the management of distress in this patient population and their family caregivers. Symptoms of distress vary based on multiple factors (e.g., pain, cognitive status, type of caregiver) and can be masked in the cognitively impaired due to communication difficulties. The purpose of this study was to examine whether resident and family caregiver distress and strain are different among three NH resident groups based on diagnoses: (a) Alzheimer’s, (b) other dementia disorders, and (c) non-cognitive diagnoses. This exploratory study was a secondary analysis of data collected from a longitudinal study examining end-of-life care in NHs. The sample was comprised of 1,282 pairs of NH residents and their family caregivers from two Midwestern states. Caregiver and resident distress and strain were measured with the Caregiver Strain Index and the Family Memorial Symptom Assessment Scale Global Index, respectively. ANOVA procedures were used to test for differences among the groups, and follow-up tests were conducted using Duncan/Dunnett’s T3 tests. Findings indicated significant decreases in distress (F(2,1267) = 34.16, p<.001) and strain (F(2,1267) = 10.08, p<.001) among cognitively-impaired residents from those who were cognitively intact. No significant differences were found in caregiver distress or strain based on the cognitive status of their loved one. It is uncertain whether the reported differences are attributable to communication difficulties of the cognitively-impaired residents or whether they are experiencing less distress and strain. Research in other geographic locations using larger samples are needed to provide further insight.UNIVERSITY OF KANSAS SCHOOL OF NURSING BACHELOR OF SCIENCE IN NURSING HONORS PROGRAMSELF REPORTED HEALTH PROMOTION BEHAVIORS OF INDIVIDUALS WITH PSYCHIATRIC DISABILITIES IN A WEIGHT LOSS INTERVENTION

Cohomología de Bott-Chern
No full textEn este trabajo consideramos ciertos invariantes asociados a una variedad compleja introducidos por R. Bott y S.S. Chern como grupos de cohomología definidos a partir de la descomposición usual de la diferencial exterior de la variedad. Cuando una variedad compleja es compacta y Kähler, es decir, posee una métrica de Riemann compatible con su estructura compleja de manera que la forma fundamental asociada es simpléctica, los grupos de cohomología de Bott-Chern coinciden con los grupos de cohomología de Dolbeault. El objetivo principal del trabajo es la determinación de la cohomología de Bott-Chern de nilvariedades complejas compactas 6-dimensionales cuya estructura compleja es invariante. Ya que las nilvariedades distintas de los toros complejos no admiten métrica Kähler, los grupos de cohomología de Bott-Chern son invariantes complejos que en general no coinciden con los de Dolbeault. Para la determinación de los invariantes se utilizan resultados que nos permiten determinar la cohomología de Bott-Chern a nivel del álgebra de Lie que subyace a la nilvariedad junto con la clasificación de estructuras complejas sobre álgebras de Lie nilpotentes 6-dimensionales. Como aplicación de este estudio introducimos y calculamos para nilvariedades 6-dimensionales M un invariante complejo que puede interpretarse como una medida de la "no-Kähleridad" de M y mostramos el comportamiento de este invariante por deformación de la estructura compleja
Bott–Chern Laplacian on almost Hermitian manifolds
No full textLet (M, J, g, ω) be a 2n-dimensional almost Hermitian manifold. We extend the definition of the Bott–Chern Laplacian on (M, J, g, ω) , proving that it is still elliptic. On a compact Kähler manifold, the kernels of the Dolbeault Laplacian and of the Bott–Chern Laplacian coincide. We show that such a property does not hold when (M, J, g, ω) is a compact almost Kähler manifold, providing an explicit almost Kähler structure on the Kodaira–Thurston manifold. Furthermore, if (M, J, g, ω) is a connected compact almost Hermitian 4-manifold, denoting by hBC1,1 the dimension of the space of Bott–Chern harmonic (1, 1)-forms, we prove that either hBC1,1=b- or hBC1,1=b-+1. In particular, if g is almost Kähler, then hBC1,1=b-+1, extending the result by Holt and Zhang (Harmonic forms on the Kodaira–Thurston manifold. arXiv:2001.10962, 2020) for the kernel of Dolbeault Laplacian. We also show that the dimensions of the spaces of Bott–Chern and Dolbeault harmonic (1, 1)-forms behave differently on almost complex 4-manifolds endowed with strictly locally conformally almost Kähler metrics. Finally, we relate some spaces of Bott-Chern harmonic forms to the Bott–Chern cohomology groups for almost complex manifolds, recently introduced in Coelho et al. (Maximally non-integrable almost complex structures: an h-principle and cohomological properties, arXiv:2105.12113, 2021)
