This has led to a considerable change of our view on stellar systems. These systems appear much more chaotic than was previously thought and subject to various instabilities leading to new paths of evolution than previously thought. The implications are fundamental for our views on the evolution of the galaxies and the universe. Such questions are addressed in this book, especially in the 8 review papers by leading experts on various aspects of the N-body problem, explaining at the graduate/postgraduate level the concepts, methods, techniques and results. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v430 606 $aStatistical physics 606 $aDynamical systems 606 $aObservations, Astronomical 606 $aAstronomy?Observations 606 $aAstrophysics 606 $aPhysics 606 $aMathematical analysis 606 $aAnalysis (Mathematics) 606 $aComplex Systems$3https://scigraph.springernature.com/ontologies/product-market-codes/P33000 606 $aAstronomy, Observations and Techniques$3https://scigraph.springernature.com/ontologies/product-market-codes/P22014 606 $aAstrophysics and Astroparticles$3https://scigraph.springernature.com/ontologies/product-market-codes/P22022 606 $aMathematical Methods in Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19013 606 $aNumerical and Computational Physics, Simulation$3https://scigraph.springernature.com/ontologies/product-market-codes/P19021 606 $aAnalysis$3https://scigraph.springernature.com/ontologies/product-market-codes/M12007 615 0$aStatistical physics. 615 0$aDynamical systems. 615 0$aObservations, Astronomical. 615 0$aAstronomy?Observations. 615 0$aAstrophysics. 615 0$aPhysics. 615 0$aMathematical analysis. 615 0$aAnalysis (Mathematics). 615 14$aComplex Systems. 615 24$aAstronomy, Observations and Techniques. 615 24$aAstrophysics and Astroparticles. 615 24$aMathematical Methods in Physics. 615 24$aNumerical and Computational Physics, Simulation. 615 24$aAnalysis. 676 $a523.8 702 $aGurzadyan$b V.G$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aPfenniger$b D$4edt$4http://id.loc.gov/vocabulary/relators/edt 712 12$aWorkshop on Ergodic Concepts in Stellar Dynamics$f(1993 :$eGeneva Observatory, Switzerland) 906 $aBOOK 912 $a996466720403316 996 $aErgodic concepts in stellar dynamics$91502064 997 $aUNISA
