Nonexistence of Invariant Rigid Structures and Invariant Almost Rigid Structures

We prove that certain volume preserving actions of Lie groups and their lattices do not preserve rigid geometric structures in the sense of Gromov. The actions considered are the ”exotic” examples obtained by Katok and Lewis and the first author, by blowing up closed orbits in the well known actions on homogeneous spaces. The actions on homogeneous spaces all preserve affine connections, wherea...

Rigid perfectly plastic two-dimensional polycrystals

We consider rigid–perfectly–plastic polycrystals in the two–dimensional anti– plane shear context. The yield sets of the grains are identified with rectangles in the plane centered at the origin whose sides have length 2 and 2M . The limit M → ∞ corresponds to the grains being rigid in one direction and ductile in the orthogonal direction. We show that for large values of M , there exist polycr...

Plastic masters-rigid templates for soft lithography.

We demonstrate a simple process for the fabrication of rigid plastic master molds for soft lithography directly from (poly)dimethysiloxane devices. Plastics masters (PMs) provide a cost-effective alternative to silicon-based masters and can be easily replicated without the need for cleanroom facilities. We have successfully demonstrated the use of plastics micromolding to generate both single a...

On finite rigid structures

The main result of this paper is a probabilistic construction of finite rigid structures. It yields a finitely axiomatizable class of finite rigid structures where no L∞,ω formula with counting quantifiers defines a linear order.

Categoricity Spectra for Rigid Structures

For a computable structure M , the categoricity spectrum is the set of all Turing degrees capable of computing isomorphisms among arbitrary computable copies of M . If the spectrum has a least degree, this degree is called the degree of categoricity of M . In this paper we investigate spectra of categoricity for computable rigid structures. In particular, we give examples of rigid structures wi...
