The integral cohomology rings of four-dimensional toric orbifolds

Xin Fu, Tseleung So, Jongbaek Song

Let $X (P, λ)$ be a 4-dimensional toric orbifold associated to a polygon $P$ and a characteristic function $λ$ . Assuming that $X (P, λ)$ is locally smooth over a vertex of $P$ , we dete…

A stability theorem for bigraded persistence barcodes

Anthony Bahri, Ivan Limonchenko, Taras Panov +2

We define bigraded persistent homology modules and bigraded barcodes of a finite pseudo-metric space X using the ordinary and double homology of the moment-angle complex associated…
