On growth of the number of determinants with restricted entries. (arXiv:1802.02111v1 [math.NT])
来源于:arXiv
Let $A$ be a finite subset of a field $\mathbb{F}$ and $D_n(A)$ be a set of
all matrices with entries in $A$, namely $$ D_n(A)=\{D\in \mathbb{F}\ |\
\exists a_{ij}\in A, 1 \le i,j \le n, \det\bigl((a_{ij})\bigr)=D\}, $$ where
the symbol $(a_{ij})$ defines the matrix with elements $a_{ij}$. How big is the
size of the set $D_n(A)$ comparing to the size of the set $A$? 查看全文>>
