Jumping line means1/8/2024 ![]() Generally, a landing area 8m long placed 2m from the take‑off line is recommended. The landing area is 7‑9m long depending on the distance between its nearest end and the take‑off line. This makes it possible to combine the long and triple jump with two or three take‑off boards (which can be used on both sides) on a triple jump runway. If it has a track surface on its reverse side, it can be turned over and used as part of the runway. During sport free periods, the take‑off board can be removed. In the case of a runway with a permanent surface, this requires a built‑in installation tray made of corrosion protected metal in which the take‑off board is correctly positioned. The surface of the take‑off board must be flush with the surface of the runway. The take‑off board is a white rectangle and measures 1.22m ± 0.01m long and 0.20m ± 0.002m wide and not more than 0.10m deep. The runway is usually covered with the same surface as the track. It is marked by white lines 0.05m wide or broken lines 0.05m wide, 0.10m long and 0.50m apart. The runway is 40m minimum long, 1.22m ± 0.01m wide and is measured from the beginning of the runway to the take‑off line. This allows competition in either direction by two groups of athletes simultaneously. Usually, it is placed outside the track along one of the straights with two adjacent runways with a landing area at each end.

Mulase, Motohico (1979), "Poles of instantons and jumping lines of algebraic vector bundles on P³", Japan Academy.Then a plane of V corresponds to a jumping line of this vector bundle if and only if it is isotropic for the skew-symmetric form. There is a rank 2 vector bundle over the 3-dimensional complex projective space associated to V, that assigns to each line L of V the 2-dimensional vector space L ⊥/ L. Suppose that V is a 4-dimensional complex vector space with a non-degenerate skew-symmetric form. If the bundle is generically trivial along lines, then the Jumping lines are precisely the lines such that the restriction is nontrivial. Lines such that the decomposition differs from this generic type are called 'Jumping Lines'. Given a bundle on C P n, with decomposition of the same type. Still one can gain information of this type by using the following method. This phenomenon cannot be generalized to higher dimensional projective spaces, namely, one cannot decompose an arbitrary bundle in terms of a Whitney sum of powers of the Tautological bundle, or in fact of line bundles in general. The Birkhoff–Grothendieck theorem classifies the n-dimensional vector bundles over a projective line as corresponding to unordered n-tuples of integers. The jumping lines of a vector bundle form a proper closed subset of the Grassmannian of all lines of projective space. In mathematics, a jumping line or exceptional line of a vector bundle over projective space is a projective line in projective space where the vector bundle has exceptional behavior, in other words the structure of its restriction to the line "jumps".
