Noncommutative Multivariable Operator Theory

Integral Equations and Operator Theory, 2012
Given a Hilbert space \(\mathcal{H}\), the author studies noncommutative domains \(\mathbb{D}_f^\phi(\mathcal{H})\) in \(B(\mathcal{H})^n\), generated by a positive regular free holomorphic function \(f\) and some classes of \(n\)-tuples \(\phi=(\phi_1,\dots,\phi_n)\) of formal power series in (noncommutative) indeterminates \(Z_1,\dots,Z_n\).

Introducing the Operator Theory

2016
The Operator Theory is a new theory about the hierarchical organisation of complexity in nature. The theory is based on the idea that in the space of all possible processes, a small subset exists of highly specific processes through which small objects can integrate to form new, more complex objects.

The RNA Operator Theory

Medical Hypotheses, 1982
The aim of the RNA Operator Theory is to propose a new explanation for the mechanism of certain biological control functions, including morphogenesis and brain function. It assumes the existence of a natural computing language, the vocabulary of which, in machine language form, is constituted of bytes of nucleotide bits.
