Phylogenetic trees reconstructed from molecular sequences are often considered more reliable than those reconstructed from morphological characters, in part because convergent evolution, which confounds phylogenetic reconstruction, is believed to be rarer for molecular sequences than for morphologies. However, neither the validity of this belief nor its underlying cause is known. Here comparing...

Several recent papers investigated unbounded convergences in Banach lattices. The focus of this paper is to apply the results convergence classical lattice theory from a new perspective. Combining all convergences, including order (norm, absolute weak, weak*) convergence, we characterize L-weakly compact sets, operators and M-weakly on For applications, introduce so-called statistical-unbounded...
