Functionals that penalize bending or stretching of a surface play a key role in geometric and scientific computing, but to date have ignored a very basic requirement: in many situations, surfaces must not pass through themselves or each other.

Surface-to-surface intersections [PDF]
Techniques for computing intersections of algebraic surfaces with piecewise rational polynomial parametric surface patches and intersections of two piecewise rational polynomial parametric surface patches are discussed. The techniques are classified using four categories-lattice evolution methods, marching methods, subdivision methods, and analytic ...

For primes \(p \equiv 3 \bmod 4\), we show that setting up CSIDH on the surface, i.e., using supersingular elliptic curves with endomorphism ring \(\mathbf {Z}[(1 + \sqrt{-p})/2]\), amounts to just a few sign switches in the underlying arithmetic. If \(p \equiv 7 \bmod 8\) then horizontal 2-isogenies can be used to help compute the class group action ...

Reconstruction of freeform surfaces for metrology [PDF]
The application of freeform surfaces has increased since their complex shapes closely express a product's functional specifications and their machining is obtained with higher accuracy.

On surfaces and Heegaard surfaces [PDF]
Summary: This paper is concerned with the intersection of surfaces and Heegaard surfaces in closed orientable 3-manifolds \(M\). Given a Heegaard decomposition \((M, V_ 1, V_ 2)\) it will be shown that any surface (orientable or not) in \(M\) is equivalent to a surface which intersects \(V_ 1\) in discs whose total number is limited from above by some ...

REAL SURFACES IN ELLIPTIC SURFACES [PDF]
We study the structure of complex points on real surfaces, embedded into complex elliptic surfaces. We show, for example, that any compact connected surface has a totally real embedding into a blow-up of a K3 surface. We also exhibit smooth disc bundles over compact connected orientable surfaces that have a Stein structure as Stein domains inside ...

Mutual influence of cross hatch angle and superficial roughness of honed surfaces on friction in ring-pack tribo-system [PDF]
The cylinder bore surface texture, widely produced by the honing technique, is an essential factor for a good engine performance (friction, oil consumption, running-in, wear etc.).

On-surface synthesis on a bulk insulator surface [PDF]
Abstract On-surface synthesis has rapidly emerged as a most promising approach to prepare functional molecular structures directly on a support surface. Compared to solution synthesis, performing chemical reactions on a surface offers several exciting new options: due to the absence of a solvent, reactions can be envisioned that are ...

On the genus of reducible surfaces and degenerations of surfaces [PDF]
We deal with a reducible projective surface X with so-called Zappatic singularities , which are a generalization of normal crossings. First we compute the
