Determining nonlinear balance laws in product-type domains by a single local passive boundary observation

Chaohua Duan, Hongyu Liu, Qingle Meng +1

This paper introduces an operator-theoretic paradigm for solving inverse problems in nonlinear balance laws, shifting the focus from identifying specific functional forms to recove…

A New Quasi-Singularity Formation Mechanism for Second-order Hyperbolic Equations

Huaian Diao, Xieling Fan, Hongyu Liu

This paper investigates a novel mechanism for quasi-singularity formation in both linear and nonlinear hyperbolic wave equations in two and three dimensions. We prove that over any…

Geometrical characterizations of radiating and non-radiating elastic sources and mediums with applications

Huaian Diao, Xiaoxu Fei, Hongyu Liu

In this paper, we investigate two types of time-harmonic elastic wave scattering problems. The first one involves the scattered wave generated by an active elastic source with comp…

Pattern formations of coupled PDEs with transparent boundary conditions in product-type ends and applications

Huaian Diao, Hongyu Liu, Qingle Meng +1

This paper studies pattern formations in coupled elliptic PDE systems governed by transparent boundary conditions. Such systems unify diverse areas, including inverse boundary prob…

Dislocations in a multi-layered elastic solid with applications to fault and interface identifications

Huaian Diao, Hongyu Liu, Qingle Meng

This paper investigates an elastic dislocation problem within a bounded and multi-layered solid governed by the Lamé system. We address the simultaneous reconstruction of the fault…

On quasi-Minnaert resonances in elasticity and their applications to stress concentrations

Huaian Diao, Ruixiang Tang, Hongyu Liu

This paper unveils and investigates a novel quasi-Minnaert resonance for an elastic hard inclusion embedded in a soft homogeneous medium in the sub-wavelength regime. The quasi-Min…
