Summary of scientific research In the early seventies Prof. Michael Heller studied, as one of the first cosmologists, relativistic world models with bulk viscosity dissipation. Now such models are considered to be standard, and bulk viscosity is interpreted as due to various quantum and semiquantum effects (e.g. the creation of particles in a strong gravitational field). Heller also investigated the influence of bulk viscosity in the appearance of singularities in cosmology. He has always been interested in the problem of classical singularities in relativistic physics. It turned out that to cope with this problem one has to generalize the standard concept of smooth manifold. To this end, Heller and his co-workers developed the theory of differential spaces and later on (with W. Sasin) the theory of structured spaces. Both these theories, by using algebraic methods, generalize the standard differential geometry to various 'pathological' situations. It turns out that different kinds of singularities met in general relativity can be investigated with the help of the theory of structured spaces. Although in the case of the most malicious singularities this methods fails to be adequate, it at least explains the source of the problem. Happily enough, even the most malicious singularities surrender to the methods based on so-called non-commutative geometry. These methods have been adapted and successfully applied to the singularity problem in general relativity by Heller and Sasin. The generalization of Einstein's general relativity in terms of structured spaces (the so-called Einstein algebras) has also been worked out. By changing from commutative Einstein algebras to non-commutative Einstein algebras, one obtains the version of general relativity expressed in terms of mathematical structures which are very close to those used in quantum physics. Following this similarity, Heller and Sasin have proposed a model, based on non-commutative geometry, unifying general relativity and quan tum mechanics. This model explains surprisingly well several non-local phenomena met in cosmology and quantum physics. M. Heller has written several books and about 700 papers on the history and philosophy of modern physics, and the relationship between science and theology.
