Generalizations and Applications of Border Bases
… ideals. This yields the new concept of projective border bases of homogeneous one-dimensional ideals. We show that there is a one-to-one correspondence between projective border bases and zero-dimensional closed subschemes of weighted projective spaces that have no point on the …

D-branes on Calabi-Yau Spaces
… thesis the properties of D-branes on Calabi–Yau spaces are investigated. Compactifications of type II string theories on these spaces to which D-branes are added lead to N = 1 supersymmetric gauge theories on the world-volume of these D-branes. Both the Calabi–Yau spaces and the D-branes have in …

Compact G<sub>2</sub>-orbifolds via Twisted Connected Sums and Associative 3-folds
… Connected Sum}, to the setting of $7$-orbifolds, spaces locally modeled on $\mathbb{R}^7/\Gamma$, quotients of $\mathbb{R}^7$ by finite subgroups $\Gamma$ of the group $G_2$. Our work extends previous results by Alexei Kovalev (\cite{Kov1}) and Dominic Joyce (\cite{Joy1}) on the existence of …
