Gevrey smoothing for weak solutions of the fully nonlinear homogeneous Boltzmann and Kac equations without cutoff for Maxwellian molecules [PDF]

open access: yes, 2015
It has long been suspected that the non-cutoff Boltzmann operator has similar coercivity properties as a fractional Laplacian. This has led to the hope that the homogenous Boltzmann equation enjoys similar regularity properties as the heat equation with ...

Laplacian energy of union and Cartesian product and Laplacian equienergetic graphs [PDF]

open access: yesKragujevac Journal of Mathematics, 2015
The Laplacian energy of a graph G with n vertices and m edges is defined as LE(G) = ∑ni=1 |μi-2m/n|, where μ1, μ2,...,μn are the Laplacian eigenvalues of G. If two graphs G1 and G2 have equal average vertex degrees, then LE(G1 ∪ G2) = LE(G1) + LE(G2). Otherwise, this identity is violated. We determine a term Ξ, such that LE(G1) + LE(G2) - Ξ ≤LE(G1 ∪ G2)

On the Adjacency, Laplacian, and Signless Laplacian Spectrum of Coalescence of Complete Graphs

open access: yesJournal of Mathematics, 2016
Coalescence as one of the operations on a pair of graphs is significant due to its simple form of chromatic polynomial. The adjacency matrix, Laplacian matrix, and signless Laplacian matrix are common matrices usually considered for discussion under ...

Remark on the Laplacian-energy-like and Laplacian incidence energy invariants of graphs [PDF]

open access: yesCreative Mathematics and Informatics, 2015
Let G be an undirected connected graph with n vertices and m edges, n ≥ 3, and let µ1 ≥ µ2 ≥ · · · ≥ µn−1 > µn = 0 and ρ1 ≥ ρ2 ≥ · · · ≥ ρn−1 > ρn = 0 be Laplacian and normalized Laplacian eigenvalues of G, respectively. The Laplacian-energy-like (LEL) invariant of graph G is defined as... The Laplacian incidence energy of graph is defined as LIE(

Entropy of eigenfunctions [PDF]

open access: yes, 2007
We study the high--energy limit for eigenfunctions of the laplacian, on a compact negatively curved manifold. We review the recent result of Anantharaman-Nonnenmacher giving a lower bound on the Kolmogorov-Sinai entropy of semiclassical measures, and ...

Magnetic spectral bounds on starlike plane domains [PDF]

open access: yes, 2014
We develop sharp upper bounds for energy levels of the magnetic Laplacian on starlike plane domains, under either Dirichlet or Neumann boundary conditions and assuming a constant magnetic field in the transverse direction.

Regularizing effect for some p-Laplacian systems [PDF]

open access: yes, 2019
We study existence and regularity of weak solutions for the following $p$-Laplacian system \begin{cases} -\Delta_p u+A\varphi^{\theta+1}|u|^{r-2}u=f, \ &u\in W_0^{1,p}(\Omega),\\-\Delta_p \varphi=|u|^r\varphi^\theta, \ &\varphi\in W_0^{1,p}(\Omega), \end{

Characterizing trees with large Laplacian energy

open access: yesLinear Algebra and its Applications, 2014
We investigate the problem of ordering trees according to their Laplacian energy. More precisely, given a positive integer $n$, we find a class of cardinality approximately $\sqrt{n}$ whose elements are the $n$-vertex trees with largest Laplacian energy.

Aggregating distributed energy resources for grid flexibility services: A distributed game theoretic approach

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView., 2023
Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the
