On Rigid and Infinitesimal Rigid Displacements in Three-Dimensional Elasticity

Let Ω be an open connected subset of R and letΘ be an immersion from Ω into R. It is first established that the set formed by all rigid displacements, i.e., that preserve the metric, of the open set Θ(Ω) is a submanifold of dimension 6 and of class C∞ of the space H(Ω). It is then shown that the vector space formed by all the infinitesimal rigid displacements of the same set Θ(Ω) is nothing but...

Three Dimensional DNA Structures in

We show that 3-dimensional graph structures can be used for solving computational problems with DNA molecules. Vertex building blocks consisting of k-armed (k = 3 or k = 4) branched junction molecules are used to form graphs. We present procedures for the 3-SAT and 3-vertex-colorability problems. Construction of one graph structure (in many copies) is suucient to determine the solution to the p...
