Co-Higgs bundles of Schwarzenberger type and the determinant morphism
Kuntal Banerjee
We identify images of the determinant morphism of trace-free co-Higgs bundles modeled on rank 2 Schwarzenberger bundles.

A generalized spectral correspondence
Kuntal Banerjee, Steven Rayan
We explore a strong categorical correspondence between isomorphism classes of sheaves of arbitrary rank on a given algebraic curve and twisted pairs on another algebraic curve, mos…

Very stable and wobbly loci for elliptic curves
Kuntal Banerjee, Steven Rayan
We explore very stable and wobbly bundles, twisted in a particular sense by a line bundle, over complex algebraic curves of genus . We verify that twisted stable bundles on an e…
