Browse Hypergeometric Families

The table gives for each degree $d$ and weight $w$ shown, the number of corresponding hypergeometric families.

Families above are separated by type – those with odd weight and even degree are symplectic, otherwise they are orthogonal. Boxes are blank for combinations of weight and degree which cannot occur.

Find a specific HGM

Search by label an HGM label encoding the triple $(A, B, t)$

Search for families of HGMs

Enter values into one or more boxes to restrict the list of families returned.

Degree e.g. 4 Weight e.g. 3
Family Hodge vector e.g. [1,1,1,1] $A$ e.g. [3,2,2] $B$ e.g. [6,4]
Prime $p$ $A_p$ e.g. [2,2,1,1] $B_p$ e.g. [2,2,1,1]
$A^\perp_p$ e.g. [2,2,1,1] $B^\perp_p$ e.g. [2,2,1,1]

Search for individual HGMs

Enter values into the boxes above and the boxes below to obtain the list of corresponding hypergeometric motives.
Conductor e.g. a value, like 32, a list, like 32,64, or a range like 1..10000
Hodge vector e.g. [1,1,1,1]
Specialization point $t$ e.g. 3/2 (1 has an associated degree drop and is always in the database)
Root number $\epsilon$ 1 or -1, with -1 occurring only in the symplectic case
