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 ...

Dependence Uncertainty Bounds for the Expectile of a Portfolio
Risks, 2015 We study upper and lower bounds on the expectile risk measure of risky portfolios when the joint distribution of the risky components is not fully specified.

Lower and upper bounds of shortest paths in reachability graphs
International Journal of Mathematics and Mathematical Sciences, 2004 We prove the following property for safe marked graphs, safe conflict-free Petri nets, and live and safe extended free-choice Petri nets. We prove the following three results. If the Petri net is a marked graph, then the length of the shortest path is at

Gilbreath Equation, Gilbreath Polynomials, and Upper and Lower Bounds for Gilbreath Conjecture
Mathematics, 2023 Let S=s1,…,sn be a finite sequence of integers. Then, S is a Gilbreath sequence of length n, S∈Gn, iff s1 is even or odd and s2,…,sn are, respectively, odd or even and minKs1,…,sm≤sm+1≤maxKs1,…,sm,∀m∈1,n.

Maximum common subgraph: some upper bound and lower bound results [PDF]
BMC Bioinformatics, 2006 Structure matching plays an important part in understanding the functional role of biological structures. Bioinformatics assists in this effort by reformulating this process into a problem of finding a maximum common subgraph between graphical representations of these structures. Among the many different variants of the maximum common subgraph problem,

Upper and Lower Bounds of Scattering Phases [PDF]
Progress of Theoretical Physics, 1951 A general method is developed for a rigorous estimation to upper and lower bounds of scattering phases in the variational methods applied to one-dimensional problems. It is also possible to estimate the mean error of the approximate wave function itself.

New upper and lower bounds for the upper incomplete gamma function
Results in Applied MathematicsSome new upper and lower bounds for the upper incomplete gamma function Γ(a,x) are presented. Some of the bounds are given for all real x>0 and some are for only certain combinations of a and x.

Upper and lower bounds on the integrated null energy in gravity
Journal of High Energy Physics, 2019 We prove a lower bound on the integrated null energy along achronal geodesic segments using induced gravity on a brane in AdS/CFT. The bound follows from the assumption that bulk causality respects brane causality, and matches a bound recently ...

Upper and lower bounds for competitive group testing
Discrete Applied Mathematics, 2023 We consider competitive algorithms for adaptive group testing problems. In the first part of the paper, we develop an algorithm with competitive constant c < 1.452 thus improving the up to now best known algorithms with constants 1.5+epsilon from 2003.

Some Refinements and Generalizations of I. Schur Type Inequalities
The Scientific World Journal, 2014 Recently, extensive researches on estimating the value of e have been studied. In this paper, the structural characteristics of I. Schur type inequalities are exploited to generalize the corresponding inequalities by variable parameter techniques.
