Rayleigh Waves in a Homogeneous Magneto-Thermo Voigt-Type Viscoelastic Half-Space under Initial Surface Stresses

This paper deals with the propagation of magneto-thermo Rayleigh waves in a homogeneous viscoelastic half-space under initial stress. It has been observed that velocity of Rayleigh waves depends on viscosity, magnetic field, temperature and initial stress of the half-space. The frequency equation for Rayleigh waves under the effect of magnetic field, stress and temperature for both viscoelastic...

Linear and nonlinear Rayleigh–Bénard–Marangoni instability with surface deformations

Thermoconvective instabilities in a bilayer liquid–gas system with a deformed interface are investigated. In the first part of the work which is devoted to a linear approach, emphasis is put on the role of the upper gas layer on the instability phenomenon. The condition to be satisfied by the gas to remain purely conductive is established. The so-called Oberbeck–Boussinesq approximation is disc...

Connected Surface of General Type

Motivated by a recent result of Y. Lee and the second author [9], we construct a simply connected minimal complex surface of general type with pg = 0 and K 2 = 3 using a rational blow-down surgery and Q-Gorenstein smoothing theory. In a similar fashion, we also construct a new simply connected symplectic 4-manifold with b + 2 = 1 and K 2 = 4.

A Simply Connected Surface of General Type

In this paper we construct a simply connected, minimal, complex surface of general type with pg = 0 and K 2 = 2 using a Q-Gorenstein smoothing theory and a rational blow-down surgery.
