▁and ▁Mathemat ics ▁Research ▁Centre ▁at ▁the ▁new ▁University ▁of ▁War wick ▁in ▁ 1 9 6 4 . ▁In ▁his ▁own ▁words ▁I ▁was ▁ 3 8 ▁and ▁had ▁developed ▁some ▁fairly ▁strong ▁ideas ▁on ▁how ▁to ▁run ▁a ▁department ▁and ▁create ▁a ▁Mathemat ics ▁Institute : ▁I ▁wanted ▁to ▁combine ▁the ▁flex ibility ▁of ▁options ▁that ▁are ▁common ▁in ▁most ▁American ▁univers ities , ▁with ▁the ▁kind ▁of ▁tutorial ▁care ▁to ▁be ▁found ▁in ▁Oxford ▁and ▁Cambridge . ▁ ▁Ze eman ' s ▁style ▁of ▁leadership ▁was ▁inform al , ▁but ▁inspir ational , ▁and ▁he ▁rapidly ▁took ▁War wick ▁to ▁international ▁recognition ▁for ▁the ▁quality ▁of ▁its ▁mathematical ▁research . ▁The ▁first ▁six ▁appoint ments ▁he ▁made ▁were ▁all ▁in ▁topology , ▁en abling ▁the ▁department ▁to ▁immediately ▁become ▁intern ation ally ▁compet itive , ▁followed ▁by ▁six ▁in ▁algebra , ▁and ▁finally ▁six ▁in ▁analysis ▁and ▁six ▁in ▁applied ▁mathematics . ▁He ▁was ▁able ▁to ▁trade ▁four ▁academic ▁appoint ments ▁for ▁fund ing ▁that ▁enabled ▁Ph D ▁students ▁to ▁give ▁under grad uate ▁super vis ions ▁in ▁groups ▁of ▁two ▁for ▁the ▁first ▁two ▁years , ▁in ▁a ▁manner ▁similar ▁to ▁the ▁tutorial ▁system ▁at ▁Oxford ▁and ▁Cambridge . ▁ ▁He ▁remained ▁at ▁War wick ▁until ▁ 1 9 8 8 , ▁but ▁from ▁ 1 9 6 6 ▁to ▁ 1 9 6 7 ▁he ▁was ▁a ▁visit ing ▁professor ▁at ▁the ▁University ▁of ▁California ▁at ▁Ber keley , ▁after ▁which ▁his ▁research ▁turned ▁to ▁dynam ical ▁systems
