Az előadás témája:

I will review aspects of twistor theory, its aims and achievements  spanning the last five decades. In the twistor approach, space--time is  secondary with events being derived objects that correspond to compact  holomorphic curves in a complex three--fold -- the twistor space. Solutions to linear and nonlinear equations of mathematical physics: anti-self-duality (ASD) equations on Yang--Mills, or conformal curvature can be encoded into twistor cohomology. These twistor correspondences yield explicit examples of Yang--Mills, and gravitational instantons.

Finally I shall  discuss the Newtonian limit of twistor theory, and its possible role in  Penrose's proposal for a role of gravity in quantum collapse of a wave function.
