Generalizing pseudospherical drawings, we introduce a new class of simple drawings, which we call separable drawings. In a separable drawing, every edge can be closed to a simple curve that intersects each other edge at most once. Curves of different

In this article we study the extendability of a smooth projective variety by degenerating it to a ribbon. We apply the techniques to study extendability of Calabi-Yau threefolds $X_t$ that are general deformations of Calabi-Yau double covers of Fano

Fractional matching extendability is a concept that brings together two widely studied topics in graph theory, namely that of fractional matchings and that of matching extendability. A {\em fractional matching} of a graph $\Gamma$ with edge set $E$ i

In 2012, MIKLAVIC et al gave the definition of the l-HC- extendability by combining the extendability of connected graphs with hamiltonicity. Based on their study, a connected graph Γ is l-HC- extendable if it contains a path of length l and every s

Extending the work of Liu--Mubayi--Reiher~\cite{LMR23unif} on hypergraph Tur\'{a}n problems, we introduce the notion of vertex-extendability for general extremal problems on hypergraphs and develop an axiomatized framework for proving strong stabilit

We investigate the "natural" locus of definition of Abel-Jacobi maps. In particular, we show that, for a proper, geometrically reduced curve C -- not necessarily smooth -- the Abel-Jacobi map from the smooth locus C^{sm} into the Jacobian of C does n

Sufficient conditions for matching extendability in terms of the Zeroth-order General Randi\'c Index

Wang, Shuai, Su, Guifu
Topological indices are important bridge between graph theory and chemical applications. In this paper, we will provide some sufficient conditions for a graph to be $k$-extendable graphs, $n$-factor-critical graphs and $(n,k,d)$-graphs in terms of a
