Torsion cycles on Fermat varieties
Ramesh Sreekantan
A theorem of Manin and Drinfeld states that any divisor of degree on the cusps of a modular curve is torsion in the Jacobian. An elegant proof of this result was provided by El…
Equations defining Jacobians with Real Multiplication
Rahul Mistry, Ramesh Sreekantan
If is genus curve a natural question to ask is: Under what conditions on does the Jacobian have real multiplication by…
Algebraic cycles and values of Green's functions -- Products of Elliptic Curves
Ramesh Sreekantan
Gross and Zagier defined certain `higher Green's functions' on products of modular curves and conjectured that the value of these functions at complex multiplication points should…
Motivic cycles on K3 double covers of del Pezzo surfaces
Ramesh Sreekantan
We construct motivic cohomology cycles in the group where is a K3 surface obtained as a double cover of a del Pezzo surface branched at…
Indecomposable motivic cycles on K3 surfaces of degree 2
Ramesh Sreekantan
In this paper we construct new indecomposable motivic cycles in the group where X is a degree 2 K3 surface. This generalizes our construction i…
Singularities of Feynman Integrals
Tanay Pathak, Ramesh Sreekantan
In this paper, we study the singularities of Feynman integrals using homological techniques. We analyse the Feynman integrals by compactifying the integration domain as well as the…
