The grand four - affine invariant globalizations of Netwon’s method
Speaker: Peter Deuflhard
Zuse Institute Berlin, Germany
Date: Friday, June 8, 2018
Place: USI Lugano Campus, room SI-003, Informatics building (Via G. Buffi 13)
Time: 09:00-10:00



Four affine invariance classes (affine covariance, affine contravariance, affine conjugacy, affine similarity) for nonlinear problems lead to four different classes of adaptive global Newton algorithms.
Affine covariance applies to boundary value problems for differential equations (both ODEs and PDEs), affine contravariance applies to Fredholm integral equations, affine conjugacy leads to convex optimization, and, last but not least, affine similarity leads to pseudo-continuation methods for equilibrium problems in time dependent ODEs or PDEs. For the latter invariance class rather recent results are presented.
