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.

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…

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…
