  "body": "\n## Summary\n\nThe Riemann P-symbol is a notation for the solutions of [[Riemann's differential equation|RS8Z48E784]].\nIt is a table listing the three singular points, the two exponents at each, and the variable.\nSince the equation is determined by these data, the symbol names its whole two-dimensional space of solutions.\nSimple rules tell how the symbol changes under a [[Möbius transformation|0SG74WBFA2]] of the variable and under multiplication by powers.\nThese rules turn many transformation formulas of the [[hypergeometric function|463X5V31D9]] into bookkeeping.\n\n## Explanations\n\n### L1 human\n\nInstead of writing a long differential equation, one writes a small table with three columns.\nEach column gives a singular point and the two powers that the solutions show near it.\nThe table stands for all solutions of the equation with that data.\nFor example, the hypergeometric function belongs to the table with columns $(0; 0, 1-c)$, $(\\infty; a, b)$ and $(1; 0, c-a-b)$.\nMoving the points by a Möbius map or multiplying by powers just changes entries of the table in a predictable way.\n",
