The positive Schur property on positive projective tensor products and spaces of regular multilinear operators

Geraldo Botelho, Qingying Bu, Khazhak Navoyan

We characterize the positive Schur property in the positive projective tensor products of Banach lattices, we establish the connection with the weak operator topology and we give n…

Orthogonally additive holomorphic maps between C*-algebras

Qingying Bu, Ming-Hsiu Hsu, Ngai-Ching Wong

Let $A, B$ be C*-algebras, $B_{A} (0; r)$ the open ball in $A$ centered at $0$ with radius $r > 0$ , and $H : B_{A} (0; r) \to B$ an orthogonally additive holomorphic map. If $H$ is zero product…

Diagonals of injective tensor products of Banach lattices with bases

Donghai Ji, Byunghoon Lee, Qingying Bu

In this paper, we show that four main diagonal spaces of injective tensor products are pairwise isometrically isomorphic. When E is a Banach lattice, we show that the tensor diagon…

Orthogonally additive and orthogonally multiplicative holomorphic functions of matrices

Qingying Bu, Chingjou Liao, Ngai-Ching Wong

Let $H : M_{m} \to M_{m}$ be a holomorphic function of the algebra $M_{m}$ of complex $m \times m$ matrices. Suppose that $H$ is orthogonally additive and orthogonally multiplicative on self…

The 2-concavification of a Banach lattice equals the diagonal of the Fremlin tensor square

Qingying Bu, Gerard Buskes, Alexey I. Popov +2

We investigate the relationship between the diagonal of the Fremlin projective tensor product of a Banach lattice $E$ with itself and the 2-concavification of $E$ .
