Functions preserving operator means

Trung Hoa Dinh, Hiroyuki Osaka, Shuhei Wada

Let $σ$ be a non-trivial operator mean in the sense of Kubo and Ando, and let $O M_{+}^{1}$ the set of normalized positive operator monotone functions on $(0, \infty)$ . In this paper, w…

A factorization property of positive maps on $C^{*}$ -algebras

B. V. Rajarma Bhat, Hiroyuki Osaka

The purpose of this short note is to clarify and present a general version of an interesting observation by Piani and Mora (Physic. Rev. A 75, 012305 (2007)), linking complete posi…

The order- $n$ minors of certain $(n + k) \times n$ matrices

Priyabrata Bag, Santanu Dey, Masaru Nagisa +1

We determine sufficient conditions for certain classes of $(n + k) \times n$ matrices $E$ to have all order- $n$ minors to be nonzero. For a special class of $(n + 1) \times n$ matrices…

Tracially sequentially-split $^{}$ -homomorphisms between $C^{}$ -algebras II

Hyun Ho Lee, Hiroyuki Osaka

We study a pair of $C^{*}$ -algebras by associating a $*$ -homomorphism from $A$ to $B$ allowing an approximate left-inverse to the sequence algebra of $A$ in a manner reminiscent of s…
