Minimal measures beyond Mather
For a positive definite Lagrangian, the minimal measure was defined in terms of first homology or cohomology class. For a configuration manifold that has a larger fundamental group than its first homology grou...

Non-intrusive polynomial chaos expansion for robust topology optimization of truss-like continuum under random loads
This paper dedicates to presenting an uncertainty analysis framework for robust topology optimization (RTO) based on truss-like material model that integrates non-intrusive polynomial chaos expansion (PCE) app...

Uniform Asymptotic Formulas of Ranks and Cranks for Cubic Partitions
In this paper, we establish uniform asymptotic formulas for the rank and crank statistics of cubic partitions. This partly improves upon the asymptotic results established by Kim–Kim–Nam in 2016.

Rankin–Cohen brackets of Hilbert Hecke eigenforms
Over any fixed totally real number field with narrow class number one, we prove that the Rankin–Cohen bracket of two Hecke eigenforms for the Hilbert modular group can only be a Hecke eigenform for dimension r...

Existence and Stability of Fuzzy Slightly Altruistic Equilibrium for a Class of Generalized Multiobjective Fuzzy Games
We mainly study the existence, structural stability and robustness of fuzzy slightly altruistic equilibria for a class of generalized multiobjective fuzzy games which are expressed as

Open AccessTriple Mixed Integral Transformation and Applications for Initial-Boundary Value Problems
In this paper, we establish a new integral transformation method for solving the initial-boundary value problems of the partial differential equations. The method is a combined expression mainly based on the t...

Sequential good lattice point sets for computer experiments
Sequential Latin hypercube designs (SLHDs) have recently received great attention for computer experiments, with much of the research restricted to invariant spaces. The related systematic construction methods...

Peer effect and dynamic ALM games among insurers
Technology advances have enhanced competition in insurance industry. This paper investigates a class of dynamic asset and liability management(ALM) games among insurers with mean-variance of relative log retur...

Open Access3-pre-Leibniz Algebras, Deformations and Cohomologies of Relative Rota-Baxter Operators on 3-Leibniz Algebras
In this paper, first we introduce the notions of 3-pre-Leibniz algebras and relative Rota-Baxter operators on 3-Leibniz algebras. We show that a 3-pre-Leibniz algebra gives rise to a 3-Leibniz algebra and a re...

A Fuglede type conjecture for discrete Gabor bases
This paper addresses the link between the characterization of spectral sets for orthogonal Fourier bases in \({\mathbb {Z}}_n^2\) ...

Tumor Growth with a Necrotic Core as an Obstacle Problem in Pressure
Motivated by the incompressible limit of a cell density model, we propose a free boundary tumor growth model where the pressure satisfies an obstacle problem on an evolving domain

Efficient and Exact Multimarginal Optimal Transport with Pairwise Costs
We address the numerical solution to multimarginal optimal transport (MMOT) with pairwise costs. MMOT, as a natural extension from the classical two-marginal optimal transport, has many important applications ...

Propagation Dynamics for a Degenerate Delayed System with Nonlocal Dispersal in Periodic Habitats
In this paper, we study the existence of spread speeds and periodic traveling waves for a class of space–time periodic and degenerate cooperative systems with nonlocal dispersal and delays. In order to charact...

Quasi-shadowing for ℤd-actions
A diffeomorphism is non-uniformly partially hyperbolic if it preserves an ergodic measure with at least one zero Lyapunov exponent. We prove that a C1-smooth ℤd-action has the quasi-shadowing property if one of t...
