Generalized multiplicities of edge ideals
Journal of Algebraic Combinatorics: An International Journal (KLU-JACO), Volume 47, Issue 3Pages 441–472https://doi.org/10.1007/s10801-017-0781-3We explore connections between the generalized multiplicities of square-free monomial ideals and the combinatorial structure of the underlying hypergraphs using methods of commutative algebra and polyhedral geometry. For instance, we show that the j-...

VDB: High-resolution sparse volumes with dynamic topology
ACM Transactions on Graphics (TOG), Volume 32, Issue 3Article No.: 27, Pages 1–22https://doi.org/10.1145/2487228.2487235We have developed a novel hierarchical data structure for the efficient representation of sparse, time-varying volumetric data discretized on a 3D grid. Our “VDB”, so named because it is a Volumetric, Dynamic grid that shares several characteristics ...
