Primal or dual strong-duality in nonconvex optimization and a class of quasiconvex problems having zero duality gap
(2017)
Primal or dual strong-duality (or min-sup, inf-max duality) in nonconvex optimization is revisited in view of recent literature on the subject, establishing, in particular, new characterizations for the second case. This ...
The gas metallicity gradient and the star formation activity of disc galaxies
(2016)
We study oxygen abundance profiles of the gaseous disc components in simulated galaxies in a hierarchical universe. We analyse the disc metallicity gradients in relation to the stellar masses and star formation rates of ...
A Near-Infrared Spectroscopic Survey of K-selected Galaxies at z ~ 2.3: Redshifts and Implications for Broadband Photometric Studies
(2008)
Using the Gemini Near-InfraRed Spectrograph (GNIRS), we have completed a near-infrared spectroscopic survey for K-bright galaxies at z~2.3, selected from the MUSYC survey. We derived spectroscopic redshifts from emission ...
