The classical modular form database currently contains information for all newforms of level , weight , character , for which any of the following hold:
- ;
- trivial and ;
- and ;
- and ;
- and ;
- and and .
- , is trivial, and or is prime.
In addition to the newspaces identified above, there are 131 newspaces that are present because they contain the minimal twist of a newform in one of the newspaces above.
For each newform with q-expansion the database contains the integers for , and when the level is at most and the dimension of is at most , the algebraic integers for expressed in terms of an explicit basis for the coefficient ring . For this data is available for all , and for , for all (these values exceed both the Sturm bound and in every case). When the level is at most and the dimension of is at most Hecke characteristic polynomials for primes are also available.
For each newform of level and each embedding the complex numbers are available as floating point numbers with a precision of at least bits (separately, for both real and imaginary parts); this information is available for all newforms, regardless of their dimension, even when algebraic are not available (for the same ranges of as above).
Dimension tables are available for all newspaces with , and also for those with and , and those with and . For newspaces in these ranges with we have also computed the first coefficients of the trace form of the newspace.
Not every invariant of every newform has been computed (this is computationally infeasible). Below is completeness information for some specific invariants:
-
The following information is available for every newform of level : level, weight, character, dimension, analytic conductor, Sato-Tate group, trace form, complex embedding data, all self twists, all inner twists, all twists to other newforms in the database, the minimal twist, and an upper bound on the analytic rank.
-
The following information is available for every newform of dimension at most and level , and also for every weight one newform: coefficient field, exact algebraic coefficient data, generators for the coefficient ring, and a lower bound on the index of the coefficient ring in the ring of integers of the coefficient field.
-
The following information is available for every weight one newform: projective image and projective field.
-
In cases where the odd 2-dimensional Artin representation corresponding to a weight one newform is present in the LMFDB, it is listed as a related object and the Artin image and Artin field of the weight one newform are available, and this information is also available in some cases where a twist of a weight one newform has a corresponding Artin representation in the LMFDB, even though the twisted Artin representation is not in the LMFDB. As of January 2020 this applies to about 30% of the weight one newforms in the database.
-
The database includes all of the 43 newforms that can be expressed as eta quotients [10.1090/S0002-9947-96-01743-6, MR:1376550].
-
Stark units for are available for weight 1 newforms of dimension 1.
