The proposed revisit to a classical problem in fluid–structure interaction is due to an interest in the analysis of the narrow resonances corresponding to a low-frequency fluid-borne wave, inspired by modeling and design of metamaterials. In this cas... Read More about A revisit to the plane problem for low-frequency acoustic scattering by an elastic cylindrical shell.

On the incremental equations in surface elasticity (2024)
Journal Article

We derive the incremental equations for a hyperelastic solid that incorporate surface tension effect by assuming that the surface energy is a general function of the surface deformation gradient. The incremental equations take the same simple form as... Read More about On the incremental equations in surface elasticity.

The membership problem for subsemigroups of GL2(Z) is NP-complete (2023)
Journal Article

We show that the problem of determining if the identity matrix belongs to a finitely generated semigroup of 2x2 matrices from the General Linear Group GL(2,Z) is solvable in NP. We extend this to prove that the membership problem is decidable in NP f... Read More about The membership problem for subsemigroups of GL2(Z) is NP-complete.

Decision Questions for Probabilistic Automata on Small Alphabets (2023)
