Gaps in the cloud cover? Comparing extinction measures in spiral disks
B. W. Holwerda, M. Meyer, M. Regan +11
Dust in galaxies can be mapped by either the FIR/sub-mm emission, the optical or infrared reddening of starlight, or the extinction of a known background source. We compare two dus…
The Opacity of Spiral Galaxy Disks VIII: Structure of the Cold ISM
B. W. Holwerda, B. Draine, K. D. Gordon +6
The quantity of dust in a spiral disk can be estimated using the dust's typical emission or the extinction of a known source. In this paper, we compare two techniques, one based on…
Necessary Conditions for Schur-Positivity
Peter R. W. McNamara
In recent years, there has been considerable interest in showing that certain conditions on skew shapes A and B are sufficient for the difference s_A - s_B of their skew Schur func…
Generalizing the notion of Koszul algebra
Thomas Cassidy, Brad Shelton
We introduce a generalization of the notion of a Koszul algebra, which includes graded algebras with relations in different degrees, and we establish some of the basic properties o…
Extremal -invariant eigenvalues of the Laplacian of -invariant metrics
Bruno Colbois, Emily B. Dryden, Ahmad El Soufi
The study of extremal properties of the spectrum often involves restricting the metrics under consideration. Motivated by the work of Abreu and Freitas in the case of the sphere $S…
