Maximum bound principles for a class of semilinear parabolic equations and exponential time differencing schemes [PDF]

open access: yesSIAM Review, 2020
The ubiquity of semilinear parabolic equations has been illustrated in their numerous applications ranging from physics, biology, to materials and social sciences.

An upper bound for the Z-spectral radius of adjacency tensors

open access: yesJournal of Inequalities and Applications, 2018
Let H $\mathcal{H}$ be a k-uniform hypergraph on n vertices with degree sequence Δ=d1≥⋯≥dn=δ $\Delta=d_{1} \geq\cdots\geq d_{n}=\delta$. In this paper, in terms of degree di $d_{i}$, we give a new upper bound for the Z-spectral radius of the adjacency ...

Uniform bounds for bounded geodesic image theorems [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 2013
Abstract We give a universal bound for the bounded geodesic image theorem of Masur–Minsky. The proof uses elementary techniques. We also give a universal bound for a stronger version of subsurface projection, this demonstrates good control over many standard subsurface projections simultaneously.

Smoothing metrics on closed Riemannian manifolds through the Ricci flow

open access: yes, 2011
Under the assumption of the uniform local Sobolev inequality, it is proved that Riemannian metrics with an absolute Ricci curvature bound and a small Riemannian curvature integral bound can be smoothed to having a sectional curvature bound.

Computing Uniform Bounds

open access: yesElectronic Notes in Theoretical Computer Science, 2002
AbstractWe investigate the computable content of the Uniform Boundedness Theorem which states that a pointwise bounded sequence of bounded linear operators on Banach spaces is also uniformly bounded. But, given the sequence, can we also effectively find the uniform bound? It turns out that the answer depends on how the sequence is “given”.

Uniform bound of the highest-order energy for three dimensional inhomogeneous incompressible elastodynamics

open access: yesCommunications in Analysis and Mechanics
We are concerned with the time growth of the highest-order energy of three-dimensional inhomogeneous incompressible isotropic elastodynamics. Utilizing Klainerman's generalized energy method, refined weighted estimates, and the Keel-Smith-Sogge estimate [

A Constant on a Uniform Bound of a Combinatorial Central Limit Theorem

open access: yes, 2009
Let n be a positive integer and Y(i, j), i, j = 1, ..., n, be random variables with finite fourth moments. Let ? be a random permutation on {1, ..., n} which independent of Y(i, j)’s. In this paper, we use Stein’s method and the technique from (Laipaporn,

Sunflowers and -intersecting families

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Let stand for the least number so that if is an arbitrary -uniform, -intersecting set system, where , and has more than elements, then contains a sunflower with petals. We give an upper bound for .

DP-colorings of uniform hypergraphs and splittings of Boolean hypercube into faces

open access: yes, 2022
We develop a connection between DP-colorings of $k$-uniform hypergraphs of order $n$ and coverings of $n$-dimensional Boolean hypercube by pairs of antipodal $(n-k)$-dimensional faces. Bernshteyn and Kostochka established that the lower bound on edges in
