The fractional dimensional theory in Lüroth expansion

Similarity:

It is well known that every x ( 0 , 1 ] can be expanded to an infinite Lüroth series in the form of x = 1 d 1 ( x ) + + 1 d 1 ( x ) ( d 1 ( x ) - 1 ) d n - 1 ( x ) ( d n - 1 ( x ) - 1 ) d n ( x ) + , where d n ( x ) 2 for all n 1 . In this paper, sets of points with some restrictions on the digits in Lüroth series expansions are considered. Mainly, the Hausdorff dimensions of the Cantor sets F φ = { x ( 0 , 1 ] : d n ( x ) φ ( n ) , n 1 } are completely determined, where φ is an integer-valued function defined on , and φ ( n ) as n .

King type modification of q -Bernstein-Schurer operators

Mei-Ying Ren, Xiao-Ming Zeng (2013)

Czechoslovak Mathematical Journal

Similarity:

Very recently the q -Bernstein-Schurer operators which reproduce only constant function were introduced and studied by C. V. Muraru (2011). Inspired by J. P. King, Positive linear operators which preserve x 2 (2003), in this paper we modify q -Bernstein-Schurer operators to King type modification of q -Bernstein-Schurer operators, so that these operators reproduce constant as well as quadratic test functions x 2 and study the approximation properties of these operators. We establish a convergence...
