Query: Existence of nontrivial logarithmic co-Higgs structure on curves   We study various aspects on nontrivial logarithmic co-Higgs structure
associated to unstable bundles on algebraic curves. We check several criteria
for (non-)existence of nontrivial logarithmic co-Higgs structures and describe
their parameter spaces. We also investigate the Segre invariants of these
structures and see their non-simplicity. In the end we also study the higher
dimensional case, specially when the tangent bundle is not semistable.
