Volume Integral Equation Method in Problems of

Preface In our course we will consider the volume integral equations in the following form) () () () () () (x f dy y u y b y x y x K x u x a Q m = − − + ∫ , 3 ≤ m. Many important classes of the wave scattering problems can be described by equations of this form; for example, this is the case for problems of electromagnetic and acoustic scattering on 3D transparent bodies. The corresponding inte...

Volume Integral Means of Holomorphic Functions

The classical integral means of a holomorphic function f in the unit disk are defined by [ 1 2π ∫ 2π 0 |f(re)| dθ ]1/p , 0 ≤ r < 1. These integral means play an important role in modern complex analysis. In this note we consider integral means of holomorphic functions in the unit ball Bn in C with respect to weighted volume measures, Mp,α(f, r) = [ 1 vα(rBn) ∫ rBn |f(z)| dvα(z) ]1/p , 0 ≤ r < 1...

The use of concept mapping and Vee diagram to calculate the volume by the integral

The concept mapping and the Vee diagram are important tools for improving the level of conceptual learning of mathematics in all educational levels that can play an important role in the learner's achievement. The purpose of this study is to use a concept mapping and Vee diagram, to calculate the volume of an object by the integral, includes the reaction of what a teacher really knows, the way ...

Published in The Aristotelian Society supplementary volume 77 (2003), pp. 249-93 BLIND REASONING

The paper challenges the inferentialist account of concept possession that Paul Boghossian takes as a premise in his account of the transmission of justification by deductive reasoning in his paper ‘Blind Reasoning’. Unorthodox speakers who reject the inferences in an alleged possession condition can still have the concept by understanding a word for it. In that sense, the inferences are not an...
