Abstract:Based on a very precise approximation to the lattice discrepancy of a Lamé disc, an asymptotic formula is established for the number of lattice points in the three-dimensional bodyfor large real x and fixed reals m, k . Particular attention is paid to the boundary points of Gaussian curvature zero. (2000): 11P21, 11N37, 11K38, 52C07.

“…Ω-estimate of the error term E(x) follows again from [14]. To obtain E(x) ≪ ≪ x 8/19 we use [11,Th. 6.8], which implies θ(1, 2, 2, 2, 2, 2, 2, 2, 2)…”
Abstract. Our paper is devoted to several problems from the field of modified divisors: namely exponential and infinitary divisors. We study the behaviour of modified divisors, sum-of-divisors and totient functions. Main results concern with the asymptotic behaviour of mean values and explicit estimates of extremal orders.

“…If we take that d = 3, n = 2, m 1 = m 2 = m, ω 1 = ω 2 = ω 3 = k, and d 1 = 1, the domain D is in the special form of (1.3). Since we only consider domains with smooth boundary we did not allow exponents m and k to be real numbers, to the contrary Krätzel and Nowak [8,9] do allow such general exponents. We mainly use harmonic analysis tools, while Krätzel and Nowak apply a "cut-into-slices"-method to reduce a three-dimensional problem to a two-dimensional one and then work carefully on the latter problem.…”
We study the lattice point problem associated with a special class of high-dimensional finite type domains via estimating the Fourier transforms of corresponding indicator functions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
