Resolvent Estimates of the Stokes Operator in Exterior Domains and Application
Journal Title: International Journal of Innovation in Science and Mathematics - Year 2019, Vol 7, Issue 1
Abstract
We consider an exterior domain Ω or smooth boundary. Our aim is to give some estimates to the resolvent of the stokes operator in exterior domains in the Lq norms. This estimates is then used to give estimate of the corresponding semi-group. We applied the preceding estimated to the nonstationary stokes initial boundary problem. A global estimate involving the velocity and the pressure is then obtained. Our method is based on the localization techniques and the Lemmas of Bogoski on the div and the problems.

Total Volume Flux from Mass Conservation in Equations of Motion on a Disk / Plate Surface
We look at mass conservation in equations of motion on a disk/plate surface. u/v, u/r, w are functions of z where (u, v, w) are velocity components of r, theta and z or (r, theta, z) in cylindrical coordinate system with...
An Investigation and Research on the Current Situation of the Teaching Skills of Young Mathematics Teachers
The development of education is the top priority of the national development. Teachers play an important role in education, and the growth of young teachers is the key to the construction of teaching staff. Although youn...
Rational Solutions to the Johnson Equation and Rogue Waves
Rational solutions to the Johnson equation are constructed as a quotient of two polynomials in x, y and t depending on several real parameters. We obtain an infinite hierarchy of rational solutions written in terms of po...

Different Mean-CVaR Models in Various Situations and its Effective Boundary
According to the framework of mean—CVaR model, CVaR is used instead of variance as a risk measurement to obtain the mean-CVaR model, and the intrinsic relationship between the two mode...
