%0 Journal Article %T Best Local Approximations by Abstract Norms with Non-homogeneous Dilations %A Yanz¨®n %A Norma %A Z¨® %A Felipe %J Revista de la Uni£¿3n Matem£¿£¿tica Argentina %D 2008 %I Uni¨®n Matem¨¢tica Argentina %X we introduce a concept of best local approximation using abstract norms and non-homogeneous dilations. the asymptotic behavior of the normalized error function as well as the limit of some net of best approximation polynomials as are studied. %K best local approximations %K function norms %K non-homogeneous dilations. %U http://www.scielo.org.ar/scielo.php?script=sci_abstract&pid=S0041-69322008000200009&lng=en&nrm=iso&tlng=en
