Solvability theorem bismarck armb?nd for the Cauchy problem to a degenerate linear evolution equation of fractional order in a Banach space is used for deriving of necessary and sufficient conditions of solvability for some arising in hydrodynamics equations systems of fractional order with respect to the time.Solutions forms for considered problem
Coal is expected to be an important energy resource for some developing countries in the coming decades; thus, the rapid classification and qualification of coal quality has an important impact on the improvement in industrial production and the reduction in pollution emissions.The traditional methods for the proximate analysis of coal are time con
Hybridization between distinct populations or species is increasingly recognized as an important process for generating biodiversity.However, the interaction between hybridization and speciation is complex, and the diverse evolutionary outcomes of hybridization are difficult to differentiate.Here we characterize potential hybridization in a species
