Principal configurations around umbilics of spacelike surfaces in null hypersurfaces of $R_{1}^{4}$

Matias Navarro, Oscar Palmas, Didier A. Solis

We study the principal configurations around an isolated $η$ -umbilical point on a generic spacelike surface $S$ immersed in a null hypersurface $M$ of Minkowski space $\mathbb{R}_1…

Isometric bending requires local constraints on free edges

Jemal Guven, Martin Michael Müller, Pablo Vázquez-Montejo

While the shape equations describing the equilibrium of an unstretchable thin sheet that is free to bend are known, the boundary conditions that supplement these equations on free…

On perfect powers that are sums of cubes of a five term arithmetic progression

Alejandro Argáez-García

We prove that the equation $(x - 2 r)^{3} + (x - r)^{3} + x^{3} + (x + r)^{3} + (x + 2 r)^{3} = y^{p}$ only has solutions which satisfy $x y = 0$ for $1 \leq r \leq 1 0^{6}$ and $p \geq 5$ prime.
