We would begin the talk with the notion of (semi)-stability of vector bundles and Higgs-bundles. A result of Simpson states that a vector bundle with a connection admits a filtration, such that, a naturally corresponding Higgs-bundle is semistable. One can start with a given filtration and try to give conditions on the filtration, such that, a connection preserving the filtration exists and the corresponding Higgs-bundle is semistable. In this talk we would discuss a few results towards semistability of Higgs-bundle from semistability of the graded components of the filtration.
