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...
