Nigel Kalton passed away on 31 August, 2010. He had work in progress and the information available so far leaves it unclear whether some articles, which were found on his desk in apparently final form, have been submitted or not. The titles are: - Hermitian operators on complex Banach lattices and a problem of Garth Dales. - Uniform homeomorphisms of Banach spaces and asymptotic structure. - Examples of uniformly homeomorphic Banach spaces. - The uniform structure of Banach spaces. We would be grateful for any information on the status of these papers, which will be submitted in Nigel's name if needed. Please kindly write to casazzap@missouri.edu and to godefroy@math.jussieu.fr if you know something. Your help is appreciated.
