A characterization of elements of best approximations

AIP Conference Proceedings, 2020
In this paper, we have proved some characterization theorems of best approximation in linear 2-normed spaces, Some of the results in inner product spaces have been extended to 2-inner product space set up and also provided some results in 2-inner product spaces and also established some equivalent conditions for orthogonality in the context of linear 2-

Characterization of Voltage Instrument Transformers Under Nonsinusoidal Conditions Based on the Best Linear Approximation [PDF]

IEEE Transactions on Instrumentation and Measurement, 2018
Voltage instrument transformers are usually tested at the rated frequency. In order to assess their performance in measuring harmonic components, typically, the frequency response function (FRF) is evaluated. Therefore, this conventional characterization

THE CHARACTERIZATION OF BEST APPROXIMATIONS IN TENSOR-PRODUCT SPACES

Analysis, 1984
Characterizations are presented for the best approximation from \(W=G\otimes C(T)+C(S)\otimes H\) to a function in C(T\(\times S)\). Here S and T are compact Hausdorff spaces, G and H are finite dimensional subspaces of C(S) and C(T) respectively. The characterizations involve measures that annihilate W.
