The Belousov-Zhabotinskii Reaction

In 1958 B. P. Belousov stumbled on that the oxidation of citric acid via bromate within the presence of cerium ions doesn't continue to equilibrium methodically and uniformly, like such a lot chemical reactions, yet really oscillates with clocklike precision among a yellow and colorless nation. See Fig. eleven. 1, p.

The Relation of Theoretical and Applied Linguistics

The connection of theoretical and utilized linguistics has in recent times caused numer­ ous debates. This quantity originated at one in all them. The essence of lots of the chapters, of them all other than Fraser's and Davies's, was once truly provided on the around desk on "The Relationships of Theoretical and utilized Linguistics," geared up through the seventh international Congress of utilized Linguistics, held in Brus­ sels, in August 1984.

Let γ=γR0 > 0 where R0 = u L∞ (IRN ×]0,+∞[) . Consider v(x, t)=u(x, t+T ), ∀(x, t) ∈ IRN ×[0, +∞[. By the periodicity of H we deduce that v is viscosity solution of ∂t v + H(x, v, Dv) = f (t), (x, t) ∈ IRN × [0, +∞[. 1 we have u(·, t + T ) − u(·, t) L∞ (IRN ) = v(·, t) − u(·, t) ≤e −γt ≤ 2e −γt L∞ (IRN ) v(·, 0) − u(·, 0) u L∞ (IRN ) L∞ (IRN ×]0,+∞[) . In particular, by taking t = s + nT , s ∈ [0, T ] we deduce that un+1 (·, s) − un (·, s) L∞ (IRN ) ≤ 2e−nT γ u L∞ (IRN ×]0,+∞[) , N and therefore there is w ∈ C(IR × IR), T periodic such that un → w|IRN ×[0,T ] uniformly on IRN × [0, T ].
