One of the most interesting questions in the operator space theory was What are the possible operator algebra products a given operator space can be equipped with?''. In my Ph.D. thesis, I answered this question using quasi-multipliers and the Haagerup tensor product. Quasi-multipliers of operator spaces were defined by Paulsen in late 2002 as...

We are going to consider the general problem whether the sum of two closed operators on a Banach space is closed on the intersection of their domains. We introduce absolute functional calculus for sectorial operators, which is stronger than $H^\infty$-calculus. Using this technique, we prove a theorem of Dore-Venni type for sums of closed...

We study an inverse nodal problem, concerned with construction of a potential function by using zeros of eigenfunctions. We shall first briefly survey on the theoretical aspect of the problem. Then we shall propose some methods of reconstruction using only zeros of one eigenfunction. Our algorithms only require finite amount of data and are...

We show that every separable Hilbertian JC*-triple can be decomposed into a countable family of Hilbertian operator spaces, each of which is representable as spaces of creation or annihilation operators. This is used to give a classification, in the category of operator spaces, of Hilbert spaces which are the range of a contractive projection on a...
