A Few New Psammocharidæ

Few New Reals

We introduce a new method for building models of CH, together with ⇧2 statements over H(!2), by forcing over a model of CH. Unlike similar constructions in the literature, our construction adds new reals, but only @1–many of them. Using this approach, we prove that a very strong form of the negation of Club Guessing at !1 known as Measuring is consistent together with CH, thereby answering a we...

A few new (?) facts about infinite elements

We discuss the (conjugated) Bubnov–Galerkin and Petrov–Galerkin infinite element (IE) discretizations to Helmholtz equation including the use of elements of locally variable order, optimal choice of IE shape functions, calculation of Echo Area (EA), and automatic hp-adaptivity. The discussion is illustrated with 2D numerical experiments. 2005 Elsevier B.V. All rights reserved. MSC classificatio...

A Few Words on Our New Format

Solving aero-acoustic or electromagnetic wave-dominated problems often requires finding accurate infinite domain solutions on a finite computational domain. One way of accomplishing this is to formulate absorbing boundary conditions through the technique of perfectly matched layers (PML). We discuss recent developments of PML methods for the absorption of acoustic waves in homogeneous mean flow...

Some New Light on a Few Classical Results

The purpose of this paper is to describe a unified approach to proving vector-valued inequalities without relying on the full strength of weighted theory. Our applications include the Fefferman-Stein and Cordoba-Fefferman inequalities, as well as the vector-valued Carleson operator. Using this approach we also produce a proof of the boundedness of the classical bi-parameter multiplier operators...
