Theory for the Rotational Deconvolution model of Turbulence with Fractional regularization
Theory the Rotational Deconvolution model Turbulence Fractional regularization Analysis of PDEs
2012/4/16
We introduce a new regularization of the rotational Navier-Stokes equations that we call the Rotational Approximate Deconvolution Model (RADM). We generalize the deconvolution type model, studied by B...
A new geometric °ow with rotational invariance
System of hyperbolic-parabolic equations rotational invariance global smooth solution time-asymptotic behavior hypersurface
2018/4/19
In this paper we introduce a new geometric flow with rotational invariance and prove that, under this kind of flow, an arbitrary smooth closed contractible hypersurface in the Euclidean space Rn+1 (n...
Chen Rotational Surfaces of Hyperbolic or Elliptic Type in the Four-dimensional Minkowski Space
Rotational surfaces Chen submanifolds four-dimensional Minkowski space
2011/1/18
We study the class of spacelike surfaces in the four-dimensional Minkowski space whose mean curvature vector at any point is a non-zero spacelike vector or timelike vector.These surfaces are determine...

The aim of this paper is to present a complete description of all linear rotational Weingarten surface into the Euclidean sphere S3. These surfaces are characterized by a linear relation aH+bK = c, wh...
