A Cohomological Lower Bound for the Transverse Ls Category of a Foliated Manifold
Let F be a compact Hausdorff foliation on a compact manifold. Let E 2 = ⊕{E 2 : p > 0, q ≥ 0} be the subalgebra of cohomology classes with positive transverse degree in the E2 term of the spectral sequence of the foliation. We prove that the saturated transverse Lusternik-Schnirelmann category of F is bounded below by the length of the cup product in E 2 . Other cohomological bounds are discussed.
متن کاملA New Lower Bound for Completion Time Distribution Function of Stochastic PERT Networks
In this paper, a new method for developing a lower bound on exact completion time distribution function of stochastic PERT networks is provided that is based on simplifying the structure of this type of network. The designed mechanism simplifies network structure by arc duplication so that network distribution function can be calculated only with convolution and multiplication. The selection of...
متن کاملA New Lower Bound for Flexible Flow Shop Problem with Unrelated Parallel Machines
Flexible flow shop scheduling problem (FFS) with unrelated parallel machines contains sequencing in flow shop where, at any stage, there exists one or more processors. The objective consists of minimizing the maximum completion time. Because of NP-completeness of FFS problem, it is necessary to use heuristics method to address problems of moderate to large scale problem. Therefore, for assessme...
