Comparison of symbolic and ordinary powers of ideals
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2002-02)
Existence of infinitely-many smooth, static, global solutions of the Einstein/Yang-Mills equations
(Springer-Verlag, 1993-01)
We prove the existence of infinitely-many globally defined singularity-free solutions, to the EYM equations with SU (2) gauge group. The solutions are indexed by a coupling constant, have distinct winding numbers, and their ...
Dual Homogeneous Forms and Varieties of Power Sums
(Birkhäuser-Verlag; Birkhäuser Verlag, Basel ; Springer Science+Business Media, 2004-10)
We review the classical definition of the dual homogeneous form of arbitrary even degree which generalizes the well-known notion of the dual quadratic form. Following the ideas of S. Mukai we apply this construction to the ...
Selective ultrafilters and homogeneity
(Elsevier, 1988-06)
We develop a game-theoretic approach to partition theorems, like those of Mathias, Taylor, and Louveau, involving ultrafilters. Using this approach, we extend these theorems to contexts involving several ultrafilters. We ...
A Primer of Commutative Algebra
(2017-03-18)
These notes collect the basic results in commutative algebra used in the rest of my
notes and books. Although most of the material is standard, the notes include a few
results, for example, the affine version of Zariski’s ...
Ondelettes and phase cell cluster expansions, a vindication
(Springer-Verlag, 1987-09)
Y. Meyer has recently developed a particularly useful o.n. basis for L 2 ( R d ). Expansions using this basis, i.e. expansions into “ondelettes” or “wavelets,” have yielded important new results in soft and hard analysis. ...
Absorbing boundary conditionsfor diffusion equations
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1995-08)
We construct and analyse a family of absorbing boundaryconditions for diffusion equations with variable coefficients, curvedartifical boundary, and arbitrary convection. It relies on the geometricidentification of the ...
Example of a potential in one-dimensional scattering problem for which there are infinitely many purely imaginary resonances
(Elsevier, 1987-10-05)
The inverse scattering theory methods are used to construct a real-valued potential q(r)[epsilon]C[infinity]0([0, R]), where R>0 is an arbitrary fixed number, which gives rise to infinitely many purely imaginary resonances. ...
