Constraining non standard recombination: A worked example [PDF]

, 2001
We fit the BOOMERANG, MAXIMA and COBE/DMR measurements of the cosmic microwave background anisotropy in spatially flat cosmological models where departures from standard recombination of the primeval plasma are parametrized through a change in the fine ...

Oscillation of Certain Neutral Delay Parabolic Equations

Journal of Mathematical Analysis and Applications, 1995
The oscillatory behavior of the neutral parabolic differential equation with continuous deviating arguments of the form \[ D_t \left[ u - \sum^m_{i = 1} c_i (t) u(x,t - r_i) \right] = a(t) \Delta u - p(x,t) u - \int^b_a q(x,t, \xi) f \biggl[ u \bigl( x,g (t, \xi) \bigr) \biggr] d \sigma (\xi) \] for \((x,t) \in \Omega \times R_+\), are reduced to the ...

OSCILLATION OF PARABOLIC NEUTRAL DELAY DIFFERENCE EQUATIONS [PDF]

Bulletin of the Korean Mathematical Society, 2004
The parabolic partial difference equation is considered which is nonlinear and of neutral type \[ \triangle_2(y_{m,n} - p_ny_{m,n-r}) + \sum_{i\in{\mathcal I}}q^{(i)}_{m,n}f(y_{m,n-\sigma_i}) = r_n\nabla^2y_{m-1,n+1} + \sum_{j\in{\mathcal J}}R_{j,n}\nabla^2y_{m-1,n+1-\gamma_j} \] with \({\mathcal I}, {\mathcal J}\) two sets of indices, \(\{y_{m,n}\} = \

Oscillation of Two-Dimensional Neutral Delay Dynamic Systems

Advances in Mathematical Physics, 2013
We consider a class of nonlinear two-dimensional dynamic systems of the neutral type (x(t)-a(t)x(τ1(t)))Δ=p(t)f1(y(t)), yΔ(t)=-q(t)f2(x(τ2(t))). We obtain sufficient conditions for all solutions of the system to be oscillatory.

Asymptotic properties of the spectrum of neutral delay differential equations

, 2009
Spectral properties and transition to instability in neutral delay differential equations are investigated in the limit of large delay. An approximation of the upper boundary of stability is found and compared to an analytically derived exact stability ...
