Real Optimization with SAP® APOn terms of Chebyshev polynomials. The origin of both, a uniform descriptor and the origin of orthogonal polynomials, can be traced back to a letter of Guido Grandi to Leibniz in 1713 on the mathematical description of the shape of flowers. In this way geometrical description and analytical tools are seamlessly combined.著名 发表于 2025-3-27 12:24:16

Inflation and the Business Cycleporous media, from Darcy’s law to Darcy–Brinkman–Forchheimer’s more general model. Using the double averaging concept (in time and in space) we explain how to obtain the more general system of equations that governs turbulent flows through porous media. For the one-equation turbulent problem in the吹牛者 发表于 2025-3-28 08:29:23
A Constructive Look at the Real Number Lineoblem that we consider has been developed by Kozak and, afterwards, improved by Henriquez. Our aim is to show the existence of mild solutions continuously depending on a parameter for the problem studied in the case when the set-valued map is Lipschitz in state variables. Moreover, as a consequence,disparage 发表于 2025-3-28 11:25:29
A Constructive Look at the Real Number Lineence operators, acting in Hilbert spaces, can be factorized using a pair of mutually adjoint first order difference operators. These classes encompass equations of hypergeometric type describing classical orthogonal polynomials of a discrete variable.
