For a Hopf algebra H over a commutative ring k and a left H-module V, the tensor endofunctors V k - and - kV are left adjoint to some kinds of Hom-endofunctors of _HM. The units and counits of these adjunctions are formally trivial as in the classical case.The category of (bi-) modules over a quasi-Hopf algebra is monoidal and some generalized versions of Hom-tensor relations have been st...
In this paper, by using the concept of spherically symmetric metric, we defne the notion of λ-projectively related metrics as an extension of projectively related metrics. We construct some non-trivial examples of λ-projectively related metrics. Let F and G be two λ-projectively related metrics on a manifold M. We find the relation between the geodesics of F and G and prove that any geodesic of...
37 In coastal forests of the Pacific Northwest, young coniferous plantations typically contain a 38 mixture of planted and natural Douglas-fir (Pseudotsuga menziesii) and western hemlock (Tsuga 39 heterophylla). Swiss needle cast (SNC) disease inhibits the growth of Douglas-fir to varying 40 degrees in these stands, depending on SNC severity. In addition to the value differential between 41 Dou...
Charles Cobb and Paul Douglas in 1928 used data from the US manufacturing sector for 1899-1922 to introduce what is known today as Cobb-Douglas production function that has been widely economic theory decades. We employ R programming language fit formulas parameters of generated by authors recently via bi-Hamiltonian approach same set utilized Douglas. conclude output elasticities total factor ...
