Attractor of Cantor Type with Positive Measure
We construct an iterated function system consisting of strictly increasing
contractions with
and such that its attractor has positive Lebesgue measure
Generalized Dimension Distortion under Mappings of Sub-Exponentially Integrable Distortion
We prove a dimension distortion estimate for mappings of sub-exponentially
integrable distortion in Euclidean spaces, which is essentially sharp in the
plane
Generalized Hausdorff dimension distortion in Euclidean spaces under Sobolev mappings
We investigate how the integrability of the derivatives of Orlicz-Sobolev
mappings defined on open subsets of affect the sizes of the
images of sets of Hausdorff dimension less than . We measure the sizes of
the image sets in terms of generalized Hausdorff measures
A realistic heat bath: theory and application to kink-antikink dynamics
We propose a new method of studying a real-time canonical evolution of
field-theoretic systems with boundary coupling to a realistic heat bath. In the
free-field case the method is equivalent to an infinite extension of the system
beyond the boundary, while in the interacting case the extension of the system
is done in linear approximation. We use this technique to study kink-antikink
dynamics in field theory in 1+1 dimensions.Comment: 21 pages including 7 figures (the shar file includes the tex file + 7
