    The objective of this thesis is to study the algebraic K-theory of exact categories. In algebraic K-theory we construct a sequence of groups, called K n , which are invari- ants of a given exact category. We look at two ...

    Gabber’s presentation lemma is a foundational result in A 1 -homotopy theory. This result can be thought of as an algebro-geometric analog of the tubular neighborhood theorem in differential geometry. Similar to tubular ...
  • DESHMUKH, NEERAJ (Dept. of Mathematics, 2021-09)
    The study of motives of algebriac stacks was initiated by Bertrand To\"{e}n for Deligne-Mumford stack, and subsequently, developed and extended by various authors to more general alegbraic stacks. There exists considerable ...
  • MAITY, DIPANKAR (2022-05)
    This text attempts to review and understand the fundamentals of ∞-categories via weak Kan complexes. We develop to some extent the construction of ∞ homs. We find a way to deal with 1-morphisms and equivalences and form ...
  • YADAV, SURAJ PRAKASH (2022-10)
    In first half of the work we prove the \A^1 connectivity of moduli stack of vector bundles on a curve, as a consequence of which we classify projective bundles on curves upto their \A^1 homotopy type. Based on joint work ...
