Webbpushforward for proper morphisms after change (p,q) to the right index, functorial pull-back for flat morphisms and are compatible with functorial pullbacks between smooth quasi-projective varieties that admit smooth projective compactifications. As corollaries, we can get the projective bundle formula and the blow-up formula.

WebbThe differential equation was solved for the flow rate distribution along the wellbore using numerical methods. Although Dikken' s model is simple, it does not properly describe the coupling between the reservoir and the wellbore equations. The assumption regarding the constant productivity index along the wellbore is not justified.

WebbInjectivity and surjectivity describe properties of a function. An injection, or one-to-one function, is a function for which no two distinct inputs produce the same output. A … Webb13. Pictorial visualizations of injective functions. (a) ‘Blobs-and-arrows diagram’. f is injective exactly when every element of B is ‘pointed’ at by at most one element of A. … WebbThe injectivity ratio, α (t), is defined as the ratio of the instantaneous to the initial injectivity indices, II and I I o, as: (13.1) α = I I / I I o The reciprocal of the “ injectivity index ” is referred to as the “impedance index” ( Bedrikovetsky et al., 2001 ). shylock\\u0027s demand
