Blow-up for self-interacting fractional Ginzburg-Landau equation
The blow-up of solutions for the Cauchy problem of fractional Ginzburg-Landau
equation with non-positive nonlinearity is shown by an ODE argument. Moreover,
in one dimensional case, the optimal lifespan estimate for size of initial data
is obtained.Comment: 8 pages, no figure
Local Well-posedness and Blow-up for the Half Ginzburg-Landau-Kuramoto equation with rough coefficients and potential
We study the Cauchy problem for the half Ginzburg-Landau-Kuramoto (hGLK)
equation with the second order elliptic operator having rough coefficients and
potential type perturbation. The blow-up of solutions for hGLK equation with
non-positive nonlinearity is shown by an ODE argument. The key tools in the
proof are appropriate commutator estimates and the essential self-adjointness
of the symmetric uniformly elliptic operator with rough metric and potential
type perturbation.Comment: 22 pages, no figure
A cascaded coding scheme for error control and its performance analysis
A coding scheme is investigated for error control in data communication systems. The scheme is obtained by cascading two error correcting codes, called the inner and outer codes. The error performance of the scheme is analyzed for a binary symmetric channel with bit error rate epsilon <1/2. It is shown that if the inner and outer codes are chosen properly, extremely high reliability can be attained even for a high channel bit error rate. Various specific example schemes with inner codes ranging form high rates to very low rates and Reed-Solomon codes as inner codes are considered, and their error probabilities are evaluated. They all provide extremely high reliability even for very high bit error rates. Several example schemes are being considered by NASA for satellite and spacecraft down link error control
Higher Order Fractional Leibniz Rule
The fractional Leibniz rule is generalized by the Coifman–Meyer estimate.
It is shown that the arbitrary redistribution of fractional derivatives for higher order with the corresponding correction terms
