Elastic Membrane Equation in Bounded and Unbounded Domains ∗

In this paper we consider weighted polynomial approximation on unbounded multidimensional domains in the spirit of the weighted version of the Weierstrass trigonometric

In this article, I discuss the need for curriculum changes in Finnish art education and how the new national cur- riculum for visual art education has tried to respond to

Another results connected with Fermat’s equation in the set of matrices are described by Ribenboim in [5].. Important problem in these investigations is to give a necessary and

At the end we analyze in detail the case of (1, n) and give a short proof of John’s main theorem which gives all the solutions of the ultrahyperbolic partial differential equation
