Factors such as mutations, genetic divergence, and hybridization all are considered evolutionary units. Within a species, genetic distance measures divergence between subgroups. Neurotransmission implies both a convergence and a divergence of information. The series can be compared to an integral to establish convergence or divergence. Differences in property rights have been cited as a possible cause of the Great Divergence. Genome duplication occurred prior to the divergence of this taxon. Therefore the velocity field has negative divergence everywhere. However, there is still some disagreement on this estimated time of divergence. Thus the gas velocity has zero divergence everywhere. However, the theory surrounding other algorithms, such as contrastive divergence is less clear. The exterior calculus allows for a generalization of the gradient, divergence and curl operators. The theory neatly accounts for the genealogical divergence. TMRCA is an estimate of the time of subclade divergence. Obviously there was a considerable divergence of opinion. The resulting beam has a larger diameter, and hence a lower divergence.
