A protagonist here is a new-type invariant for type II degenerations of K3 surfaces, which is explicit piecewise linear convex function from the interval with at most $18$ nonlinear points. Forgetting its actual function behavior, it also classifies

Owing to the spatial separation of transmitter and receiver, bistatic SAR is able to image the area in front of the moving direction of transmitter or receiver, but the geometry model is more complex than that of monostatic SAR, which brings great di

In mould manufacture the elliptical torus cutters are used for their high cutting velocity, but the special geometry also brings issues in tool path generating and machining quality controlling. In this paper a guide curve tool path generating method

Features of the geometric characteristics of fine-module ratchet teeth necessitates the use of cutting tools with special geometry of cutting edges for their manufacture. The article describes the method of shaping the cutting edges of two types of t

The Kahler potentials have been calculated on the moduli space of complex structures for two Calabi-Yau manifolds specified as hypersurfaces in weighted projective spaces. Mirror images of these manifolds have been found according to the Batyrev and

Using simple symmetry arguments we classify the ungauged $D=4$, $\mathcal{N}=2$ supergravity theories, coupled to both vector and hyper multiplets through homogeneous scalar manifolds, that can be built as the product of $\mathcal{N}=2$ and $\mathcal
