Lifting all elements in $SL_{n} (Z / q Z)$

Amitay Kamber, PÃ©ter P. VarjÃº

We show that every element of $SL_{n} (Z / q Z)$ can be lifted to an element of $SL_{n} (Z)$ of norm at most $C q^{2} lo g q$ , while there exist…

Tzviel Frostig, Oshri Machluf, Amitay Kamber +2

We introduce the causal responders detection (CARD), a novel method for responder analysis that identifies treated subjects who significantly respond to a treatment. Leveraging rec…

On the local $L^{2}$ -Bound of the Eisenstein Series

Subhajit Jana, Amitay Kamber

We study the growth of the local $L^{2}$ -norms of the unitary Eisenstein series for reductive groups over number fields, in terms of their parameters. We derive a \emph{poly-logarith…
