Let $\mathcal E$ denote the class of existentially closed II$_1$ factors. A Cartan subalgebra is a maximal abelian subalgebra whose normalizer generates the factor. Cartan-free con…

Let $\mathcal E$ denote the class of existentially closed II$_1$ factors. Tensor indecomposability conjecture. For every $P\in\mathcal E$, there do not exist II$_1$ factors $A$ and…
