Generally speaking I may say
that my interests concern Modern Mathematical
Physics. In particular I deal with several
mathematical and physical aspects of Quantum Theories and their
Mathematical Formulation and Algebraic and Axiomatic Theories of Relativistic
Quantized Fields.
- Mathematical formulation of quantum theories (also real and quaternionic Hilbert spaces, quanternionic functional analysis, especially spectral theory).
- Axiomatic, algebraic and local aspects of QFT in (generally curved) Lorentzian/Euclidean background;
- QFT in curved spacetime especially in presence of black holes, also at finite temperature;
- geometric formulation of quantum mechanics and its relation with quantum information
- QFT in cosmological models;
- QFT in the presence of conformal invariance (CFT) ;
- Some aspects of the so-called "Quantum Gravity".
- I was also concerned with some aspects of Lorentzian noncommutative geometry.
renormalization
procedure (heat-kernel and
zeta spectral function applications in QFT) look at this book I wrote
in collaboration, published by World Scientific. More recently I wrote with I.Khavkine a long review about general aspects of QFT in curved spacetime which appears a chapter of a book.A third book by Springer-Verlag about QFT in curved spacetime is forthcoming and written in collaboration with C.Dappiaggi and N.Pinamonti. I participate in the international forum LQP Crossroads |
From a mathematical point of
view, this means that I am intersted in several applications of functional
analysis (especially
topics in the theory of operator algebras and C*
algebras), global
analysis (i.e. functional analysis
on Riemannian
and Lorentzian
manifolds, using the intrinsic geometrical
structure), microlocal analysis,
differential
geometry |
