Sufficient Conditions for Tuza's Conjecture on Packing and Covering Triangles
Given a simple graph G = (V,E), a subset of E is called a triangle cover if it intersects each triangle of G. Let νt(G) and τt(G) denote the maximum number of pairwise edge-disjoint triangles in G and the minimum cardinality of a triangle cover of G, respectively. Tuza conjectured in 1981 that τt(G)/νt(G) ≤ 2 holds for every graph G. In this paper, using a hypergraph approach, we design polynom...
متن کاملYet another additivity conjecture
In quantum information theory, there are several important open problems which center around whether certain quantities are additive or not. Especially, additivity conjecture about Holevo capacity and additivity/strong superadditivity conjecture about entanglement of formation have been attracting many researchers. It recently turned out that these are equivalent to the additivity of the minimu...

متن کاملYet anther equivalent additivity conjecture
It is known that the additivity conjecture of Holevo capacity, output minimum entoropy, and the entanglement of formation (EoF), are equivalent with each other. Among them, the output minimum entropy is simplest, and hence many researchers are focusing on this quantity. Here, we suggest yet another entanglement measure, whose strong superadditivity and additivity are equivalent to the additivit...
متن کاملSufficient conditions for the additivity of stall forces generated by multiple filaments or motors.
Molecular motors and cytoskeletal filaments work collectively most of the time under opposing forces. This opposing force may be due to cargo carried by motors or resistance coming from the cell membrane pressing against the cytoskeletal filaments. Some recent studies have shown that the collective maximum force (stall force) generated by multiple cytoskeletal filaments or molecular motors may ...
