Steady dynamos in finite domains: an integral equation approach [PDF]
The paper deals with the integral equation approach to steady kinematic dynamo models in finite domains based on Biot-Savart's law. The role of the electric potential at the boundary is worked out explicitly.

On locally divided integral domains and CPI-overrings
It is proved that an integral domain R is locally divided if and only if each CPI-extension of ℬ (in the sense of Boisen and Sheldon) is R-flat (equivalently, if and only if each CPI-extension of R is a localization of R).

Reconstruction of Planar Domains from Partial Integral Measurements [PDF]
We consider the problem of reconstruction of planar domains from their moments. Specifically, we consider domains with boundary which can be represented by a union of a finite number of pieces whose graphs are solutions of a linear differential equation ...

Integrally Closed Subrings of an Integral Domain [PDF]
Let D be an integral domain with identity having quotient field K. This paper gives necessary and sufficient conditions on D in order that each integrally closed subring of D should belong to some subclass of the class of integrally closed domains; some of the subclasses considered are the completely integrally closed domains, Prufer domains, and ...

Note on Colon-Multiplication Domains
Let R be an integral domain with quotient field L. Call a nonzero (fractional) ideal A of R a colon-multiplication ideal any ideal A, such that B(A:B)=A for every nonzero (fractional) ideal B of R.

An explicit kernel-split panel-based Nystr\"om scheme for integral equations on axially symmetric surfaces [PDF]
A high-order accurate, explicit kernel-split, panel-based, Fourier-Nystr\"om discretization scheme is developed for integral equations associated with the Helmholtz equation in axially symmetric domains.

A description of n-ary semigroups polynomial-derived from integral domains [PDF]
We provide a complete classification of the n-ary semigroup structures defined by polynomial functions over infinite commutative integral domains with identity, thus generalizing G{\l}azek and Gleichgewicht's classification of the corresponding ternary ...

Boundedness of fractional operators in weighted variable exponent spaces with non doubling measures [PDF]
In the context of variable exponent Lebesgue spaces equipped with a lower Ahlfors measure we obtain weighted norm inequalities over bounded domains for the centered fractional maximal function and the fractional integral ...

The hybrid boundary-integral equation and finite-element method (BIE/FEM) is efficient for signal/power integrity analysis of multiple vias in a shared antipad (labeled as compact vias) in an arbitrarily shaped power/ground plate pair. According to field

A spectral approach to a constrained optimization problem for the Helmholtz equation in unbounded domains [PDF]
We study some convergence issues for a recent approach to the problem of transparent boundary conditions for the Helmholtz equation in unbounded domains.
