The $2$ -co-lacunary subsequence principle for arbitrary noncommutative $L_{1}$ -spaces

Jinghao Huang, Yunpeng Zhu

For every von Neumann algebra $\M$, we prove that each bounded sequence in the Haagerup space $L_1(\M)=\M_*$ admits either a norm-convergent subsequence or a $2$-co-lacunary…

Tingley's Problem for Haagerup Noncommutative $L_{p}$ -Spaces, $1 < p \neq = 2 < \infty$

Jinghao Huang, Yunpeng Zhu

We solve Tingley's problem for Haagerup noncommutative $L_{p}$ -spaces, where $1 < p \neq = 2 < \infty$ , which gives an affirmative answer to Mori's problem \cite[Problem~6.3]{Mori}.
