Notes on the divisibility of GCD and LCM Matrices
Let S = {x1,x2, . . . ,xn} be a set of positive integers, and let f be an arithmetical function. The matrices (S) f = [ f (gcd(xi,xj))] and [S] f = [ f (lcm[xi,xj])] are referred to as the greatest common divisor (GCD) and the least common multiple (LCM) matrices on S with respect to f , respectively. In this paper, we assume that the elements of the matrices (S) f and [S] f are integers and st...
متن کاملConvergence of Series of Dilated Functions and Spectral Norms of Gcd Matrices
We establish a connection between the L norm of sums of dilated functions whose jth Fourier coefficients are O(j−α) for some α ∈ (1/2, 1), and the spectral norms of certain greatest common divisor (GCD) matrices. Utilizing recent bounds for these spectral norms, we obtain sharp conditions for the convergence in L and for the almost everywhere convergence of series of dilated functions.
متن کاملON THE `p NORM OF GCD AND RELATED MATRICES
We estimate the `p norm of the n×n matrix, whose ij entry is (i, j)/[i, j], where r, s ∈ R, (i, j) is the greatest common divisor of i and j and [i, j] is the least common multiple of i and j.
متن کاملDivisibilty Properties of Gcd Ve Lcm Matrices
Let a, b and n be positive integers and let S = {x1, x2, . . . , xn} be a set of distinct positive integers. The n × n matrix (Sf ) = (f ((xi, xj))), having f evaluated at the greatest common divisor (xi, xj) of xi and xj as its ij−entry, is called the GCD matrix associated with f on the set S. Similarly, the n × n matrix [Sf ] = (f ([xi, xj ])) is called the LCM matrix associated with f on S. ...
