Operator spaces with the WEP, the OLLP and the Gurarii property (2104.05008v3)

Abstract: We construct non-exact operator spaces satisfying the Weak Expectation Property (WEP) and the Operator space version of the Local Lifting Property (OLLP). These examples should be compared with the example we recently gave of a $C^*$-algebra with WEP and LLP. The construction produces several new analogues among operator spaces of the Gurarii space, extending Oikhberg's previous work. Each of our "Gurarii operator spaces" is associated to a class of finite dimensional operator spaces (with suitable properties). In each case we show the space exists and is unique up to completely isometric isomorphism.
