HIGHLIGHTS
- who: Chebyshev set and colleagues from the (UNIVERSITY) have published the research work: 83-90 in metric linear spaces, in the Journal: (JOURNAL)
- what: The authors discuss some results on the existence and uniqueness of best approximation and best coapproximation when the underlying spaces are metric linear spaces. new kind of approximation called best coapproximation was introduced in normed linear spaces by C. Franchetti and M. Furi to obtain some characterizations of real Hilbert spaces among real Banach spaces.
SUMMARY
An element g0 ∈ G is called a best approximation (best coapproximation . . .
