On groups with D-finite cogrowth series
Mudit Aggarwal, Murray Elder, Andrew Rechnitzer
The cogrowth series of a group with respect to a finite generating set is an important combinatorial quantity that seems very difficult to compute exactly, as evidenced by the scar…

Straight polyomino tilings of rectangles and special rim-hook tableaux
Mudit Aggarwal, Hrishik Koley, Samrith Ram
We derive explicit rational generating functions for weighted tilings of rectangles by straight tiles. Our approach combines a decomposition by fault lines…

Improved bounds on the interactive capacity via error pattern analysis
Mudit Aggarwal, Manuj Mukherjee
Any interactive protocol between a pair of parties can be reliably simulated in the presence of noise with a multiplicative overhead on the number of rounds (Schulman 1996). The re…
