Mathematics of Computation, Vol. 31, No. 139 (Jul., 1977), pp. 733-737 (5 pages) An attainable bound for the infinity norm of the inverse of a whole class of symmetric circulant Toeplitz matrices is ...
In Chen and Chiang [2] and Chen, Thompson and Hung [3], the symmetric trimmed mean has been shown, for various linear models, to have the efficiency of having ...
The low-temperature dynamics of quantum systems are dominated by the low-energy eigenstates. For two-dimensional systems in particular, exotic phenomena such as topological order and anyon excitations ...
