Lower and upper bounds on independent double Roman domination in trees
Electronic Journal of Graph Theory and Applications, 2022 For a graph G = (V, E), a double Roman dominating function (DRDF) f : V → {0, 1, 2, 3} has the property that for every vertex v ∈ V with f(v)=0, either there exists a neighbor u ∈ N(v), with f(u)=3, or at least two neighbors x, y ∈ N(v) having f(x)=f(y ...

Method of intermediate problems in the theory of Gaussian quantum dots placed in a magnetic field
Condensed Matter Physics, 2006 Applicability of the method of intermediate problems to the investigation of the energy eigenvalues and eigenstates of a quantum dot (QD) formed by a Gaussian confining potential in the presence of an external magnetic field is discussed. Being smooth at

Upper and Lower Bounds on the Cost of a Map-Reduce Computation [PDF]
Proceedings of the VLDB Endowment, 2012 In this paper we study the tradeoff between parallelism and communication cost in a map-reduce computation. For any problem that is not "embarrassingly parallel," the finer we partition the work of the reducers so that more parallelism can be extracted ...

Multiple Packing: Lower and Upper Bounds
CoRR, 2022 We study the problem of high-dimensional multiple packing in Euclidean space. Multiple packing is a natural generalization of sphere packing and is defined as follows. Let $ N>0 $ and $ L\in\mathbb{Z}_{\ge2} $. A multiple packing is a set $\mathcal{C}$ of points in $ \mathbb{R}^n $ such that any point in $ \mathbb{R}^n $ lies in the intersection of ...

Some lower and upper bounds on the third ABC index
AKCE International Journal of Graphs and Combinatorics, 2016 Atom-bond connectivity (ABC) index has been applied up to now to study the stability of alkanes and the strain energy of cycloalkanes. Graovac defined the second ABC index as ABC2(G)=∑vivj∈E(G)1ni+1nj−2ninj, and Kinkar studied the upper bounds.

Computers and Mathematics with Applications, 2018 In this paper the authors deal with a class of parabolic type Kirchhoff equations, which were considered in Han and Li (2018), where global existence and finite time blow-up of solutions were studied when the initial energy was subcritical, critical and ...

Upper and lower bounds on gravitational entropy [PDF]
Journal of Cosmology and Astroparticle Physics, 2008 The gravitational entropy of the Universe is large and subtle to calculate. A lower bound is well known from supermassive black holes at the centers of galaxies, but the remainder is harder to pin down. A parametric model of clumped matter entropy is provided.

Lower and upper bounds for entanglement of Rényi-α entropy
Scientific Reports, 2016 Entanglement Rényi-α entropy is an entanglement measure. It reduces to the standard entanglement of formation when α tends to 1. We derive analytical lower and upper bounds for the entanglement Rényi-α entropy of arbitrary dimensional bipartite quantum ...
