讲座简介:
in the talk, i will introduce a new approach to construct efficient and accurate structure-preserving schemes for a class of constrained pdes. to be more specific, i will introduce how to construct positivity/bound-preserving, length-preserving, energy-dissipative schemes for a large class of pdes. i will establish stability results under a general setting, and carry out an error analysis for second-order structure-preserving schemes. finally, i will apply our approach to several typical pdes which preserve structures described above. some numerical results will be presented to validate our approach.
