A Characterization Of The Einstein Tensor In Terms Of Spinors, Ian M. Anderson, D. Lovelock
A Characterization Of The Einstein Tensor In Terms Of Spinors, Ian M. Anderson, D. Lovelock
Mathematics and Statistics Faculty Publications
All tensors of contravariant rank two which are divergence‐free on one index, concomitants of a spinor field σiAX′ together with its first two partial derivatives, and scalars under spin transformations are constructed. The Einstein and metric tensors are the only candidates.
Approximation Of Compact Homogeneous Maps, John R. Hubbard
Approximation Of Compact Homogeneous Maps, John R. Hubbard
Department of Math & Statistics Faculty Publications
Within the clasp of continuous homogeneous maps between Banach spaces, it is proved that every compact map can be uniformly approximated by finite-rank maps. This result is obtained by means of the classical metric projection on Banach spaces.

1976 Nitrogenous Fertilisers For Cereals, M. G. Mason
Experimental Summaries - Plant Research
Results from 1976 Trials on Wheat. Rates of nitrogen on wheat - soil test. In this, the second year of this programme, 49 sites were selected and soil sampled during February-March. Forty six of these trials consisted of four replications and the other three had three replications and all reps were soil sampled separately. In each rep. of the 46 trials. 20 samples were taken to 10 cm depth with pogo stick samplers. In the.other three trials 30 samples per rep. were taken. In addition, from three holes at random across each trial, bulk samples were obtained from the 0-15, …
