Numerical Experiments with Symmetric Eigensolvers
This report describes and analyzes numerical experiments carried out with various symmetric eigensolvers in the context of the material science code Wien 97. Of particular interest are the performance improvements achieved with a new Level 3 eigensolver. The techniques which lead to a signi cant speed up are (1) sophisticated blocking in the tridiagonalization step, which leads to a twosweep al...
متن کاملSymplectic and symmetric methods for the numerical solution of some mathematical models of celestial objects
In the last years, the theory of numerical methods for system of non-stiff and stiff ordinary differential equations has reached a certain maturity. So, there are many excellent codes which are based on Runge–Kutta methods, linear multistep methods, Obreshkov methods, hybrid methods or general linear methods. Although these methods have good accuracy and desirable stability properties such as A...
متن کاملOn Symmetric Numerical Semigroups
A numerical semigroup is a subset S of N such that is closed under sums, contains the zero and generates Z as a group. From this definition Ž w x. Ž one obtains see, for example, 2 that S has a conductor C i.e., the . maximum among all the natural numbers not belonging to S . A numerical semigroup S is called symmetric if for every integer z f S, C y z g S. The study of the subsemigroups of N i...
متن کاملOn Numerical Experiments with Symmetric Semigroups Generated by Three Elements and Their Generalization
We give a simple explanation of numerical experiments of V. Arnold with two sequences of symmetric numerical semigroups, S(4, 6 + 4k, 87− 4k) and S(9, 3 + 9k, 85− 9k) generated by three elements. We present a generalization of these sequences by numerical semigroups S(r 1 , r1r2 + r 2 1k, r3 − r 2 1k), k ∈ Z, r1, r2, r3 ∈ Z , r1 ≥ 2 and gcd(r1, r2) = gcd(r1, r3) = 1, and calculate their univers...
متن کاملArithmetic Properties of 1–shell Totally Symmetric Plane Partitions
In 2012, Blecher defined the combinatorial objects known as 1–shell totally symmetric plane partitions of weight n. He also proved that the generating function for f (n), the number of 1–shell totally symmetric plane partitions of weight n, is given by ∑
