Faithful odd-prime theta measure using nonzero moduli
OpenHorizontalPadicL.seededNormalizedThetaMeasure_exists_with_interpolation_v3modular-formsmodular-symbolsnumber-theoryp-adic-l-functions
For odd p, normalization of the faithfully realized theta elements gives a plus horizontal measure with the expected interpolation and trivial-character formula. Symbol comparison is assumed only at the positive, hence nonzero, conductors used in the theta construction.

/-- For odd `p`, normalization of the faithful theta system gives a plus
horizontal measure interpolating every horizontal character. Symbol comparison
is requested only at the positive, hence nonzero, conductors occurring in the
construction. -/
