Squares and difference sets in finite fields [PDF]
, 2013 For infinitely many primes p = 4k+1 we give a slightly improved upper bound for the maximal cardinality of a set B ⊂ Z p such that the difference set B−B contains only quadratic residues. Namely, instead of the ”trivial” bound |B| ≤ √p we prove |B √p

Langrangian finite element and finite difference methods for poisson problems [PDF]
, 1974 The use of Lagrangian finite element methods for solving a Poisson problem produces systems of linear equations, the global stiffness equations. The components of the vectors which are the solutions of these systems are approximations to the exact ...

Modifying Explicit Finite Difference Method by Using Radial Basis Function Neural Network [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2013 In this research, we use artificial neural networks, specifically radial basis function neural network (RBFNN) to improve the performance and work of the explicit finite differences method (EFDM), where it was compared, the modified method with an ...

Finite Difference Methods for the BSDEs in Finance
International Journal of Financial Studies, 2018 This paper gives a review of numerical methods for solving the BSDEs, especially, finite difference methods. For numerical methods of finite difference, we should divide them into three branches.

On the Finite Differences of a Polynomial [PDF]
The Annals of Mathematical Statistics, 1935 In this paper an apparently new and convenient method of finding the successive finite differences of a polynomial is considered. If operationally 4(u + rjr2) = Er7r2 4(u) = (1 + Ari)r2 4o(u) then for any polynomial f(x) of degree "n" f(x) = po xn + P, Xn-1 +--+ Pn = po(x + a)n + qll(x + a)n-I + + qln Eaf(x) = po(x + a)n + pl(x + a)n-' + + Pn Aaf(X) = (

Finite Difference Operators with a Finite-Band Spectrum [PDF]
, 2008 We study the correspondence between almost periodic difference operators and algebraic curves (spectral surfaces). An especial role plays the parametrization of the spectral curves in terms of, so called, branching divisors. The multiplication operator by the covering map with respect to the natural basis in the Hardy space on the surface is the $2d+1$-

Lattice Boltzmann model approximated with finite difference expressions
, 2017 We show that the asymptotic properties of the link-wise artificial compressibility method are not compatible with a correct approximation of fluid properties.

Finite differences of the partition function [PDF]
Mathematics of Computation, 1978 From the Hardy-Ramanujan-Rademacher formula for p ( n ) p(n) —the number of unrestricted partitions of n, it is not difficult to deduce that there exists a least positive integer n 0 ( r ) {n_0}(r) such that
