In this paper we study the generalized Burgers equation ut + (u /2)x = f(t)uxx, where f(t) > 0 for t > 0 . We show the existence and uniqueness of classical solutions to the initial value problem of the generalized Burgers equation with rough initial data belonging to L∞(R), as well it is obtained the decay rates of u in L norm are algebra order for p ∈ [1,∞[.

The distribution of guanine and cytosine nucleotides throughout a genome, or the GC content, is associated with numerous features in mammals; understanding the pattern and evolutionary history of GC content is crucial to our efforts to annotate the genome. The local GC content is decaying toward an equilibrium point, but the causes and rates of this decay, as well as the value of the equilibriu...

Double beta decay is a rare spontaneous nuclear transition in which the nuclear charge changes by two units while the mass number remains the same. It has been long recognized as a powerful tool to study lepton number conservation in general, and neutrino properties in particular. Since the lifetimes of double beta decays are so long, the experiments on double beta decay are very challenging an...
