Entropy stable reduced order modeling of nonlinear conservation laws [PDF]

Journal of Computational Physics, 2019
Reduced order models of nonlinear conservation laws in fluid dynamics do not typically inherit stability properties of the full order model. We introduce projection-based hyper-reduced models of nonlinear conservation laws which are globally conservative

Implicit extremes and implicit max–stable laws [PDF]

, 2014
Let X1, ⋯ , Xn be iid random vectors and f≥0 be a homogeneous non–negative function interpreted as a loss function. Let also k(n)=Argmaxi=1c⋯ , nf(Xi). We are interested in the asymptotic behavior of Xk(n) as n→∞. In other words, what is the distribution

Comparing Fréchet and positive stable laws [PDF]

, 2013
Let ${\bf L}$ be the unit exponential random variable and ${\bf Z}_\alpha$ the standard positive $\alpha$-stable random variable. We prove that $\{(1-\alpha)\alpha^{\gamma_\alpha} {\bf Z}_\alpha^{-\gamma_\alpha}, 0< \alpha

Operator geometric stable laws [PDF]

, 2005
Operator geometric stable laws are the weak limits of operator normed and centered geometric random sums of independent, identically distributed random vectors. They generalize operator stable laws and geometric stable laws.

Diagonal Minkowski classes, zonoid equivalence, and stable laws [PDF]

, 2020
We consider the family of convex bodies obtained from an origin symmetric convex body K by multiplication with diagonal matrices, by forming Minkowski sums of the transformed sets, and by taking limits in the Hausdorff metric.

Fisher information and convergence to stable laws [PDF]

, 2012
The convergence to stable laws is studied in relative Fisher information for sums of i.i.d. random variables.

On the ladder heights of random walks attracted to stable laws of exponent 1

, 2018
Let Z be the first ladder height of a one dimensional random walk S n = X 1 + · · · + X n with i.i.d. increments X j which are in the domain of attraction of a stable law of exponent α , 0 < α ≤ 1 . We show that P [ Z > x ] is slowly varying at infinity if

A New Proof for the Lévy Construction of Second Kind for Stable Laws [PDF]

, 2014
We give a direct proof for the "Lévy construction of second kind" for stable laws on the real line without referring to the construction of "first kind.

On stable social laws and qualitative equilibria [PDF]

, 1998
This paper introduces and investigates the notion of qualitative equilibria, or stable social laws, in the context of qualitative decision making.

Estimation of P(X < Y) Stress-Strength Reliability Measures for a Class of Asymmetric Distributions: The Case of Three-Parameter p-Max Stable Laws

Symmetry
Asymmetric distributions are frequently seen in real-world datasets due to a number of factors, such as sample biases and nonlinear interactions between the variables observed.
