The Rank Organisation Davis cut staff, reduced budgets and concentrated film production at Pinewood. Other studio facilities (in Islington) were closed, sold (Lime Grove Studios) or leased (Denham). The Rank Organisation closed Independent Producers Ltd. The policies of Davis alienated many in the industry, in particular they led film director David Lean, responsible for some of Rank's most critically and financially successful films, to look elsewhere for backing. In 1949, the company bought the Bush Radio manufacturing facility and began to diversify its interests. In the early 1960s Rank took over Murphy Radio to form the Rank Bush Murphy Group (which was eventually
Tensor rank decomposition formula_23 form a dense set formula_28: every tensor in the aforementioned space is either of rank less than the generic rank, or it is the limit in the Euclidean topology of a sequence of tensors from formula_28. In the case of real tensors, the set of tensors of rank at most formula_23 only forms an open set of positive measure in the Euclidean topology. There may exist Euclidean-open sets of tensors of rank strictly higher than the generic rank. All ranks appearing on open sets in the Euclidean topology are called typical ranks. The smallest typical rank is called the
