Resolvent Degree Calculator

Analyze polynomial complexity through dimensions, symmetry, and reductions. Compare lower bounds, upper bounds, and solvability. Study outputs, save tables, and explain results with confidence.

This page estimates study bounds for resolvent degree from dimension, symmetry, and reduction data. It is best used as an educational planning tool for algebraic problem analysis.

Calculator Form

Enter a theoretical scenario. The estimator combines degree, symmetry, parameter dimension, reduction steps, and solvability assumptions to create a study-range result.

Note: This calculator estimates study bounds from transparent scoring rules. It does not prove an exact invariant for arbitrary algebraic families.

Example Data Table

These sample rows illustrate how different families and symmetry classes can shift the estimated study range.

Case Degree Family Group m e r Estimated Range
Generic quintic study 5 Generic polynomial family Symmetric group S_n 8 5 2 2 to 4
Reduced solvable case 4 Tschirnhaus-reduced family General solvable group 5 2 3 0 to 1
Higher-degree cover 8 Galois cover study Alternating group A_n 12 8 2 4 to 6

Formula Used

This calculator uses a transparent study-bound heuristic. It combines residual parameter dimension, symmetry weight, family weight, degree pressure, and an essential-dimension proxy to estimate a lower and upper range.

1) Remaining dimension

d_r = max(m - r, 0)

2) Lower-bound estimate

L = max(L_user, ceil((d_r + 0.5s_g + 0.5e) / 4))

3) Complexity index

C = d_r + max(n-4,0)/3 + e/4 + s_g + s_f + a_s

4) Upper-bound estimate

U = min(U_user, max(L, ceil(C / 3.2)))

Where:

  • n = polynomial degree
  • m = parameter dimension
  • e = essential-dimension proxy
  • r = reduction steps already applied
  • s_g = group or symmetry weight
  • s_f = family weight
  • a_s = solvability adjustment
  • L_user and U_user = optional custom theoretical bounds

Frequently Asked Questions

1) What does this calculator actually estimate?

It estimates a study range for resolvent degree using transparent inputs and scoring rules. It is designed for exploration, teaching, and structured note-taking rather than proof generation.

2) Does it prove exact resolvent degree values?

No. Exact values are subtle and often depend on deep theory. This page creates a consistent lower-to-upper study band from your assumptions and reductions.

3) Why are degree and symmetry both included?

Degree measures algebraic size, while symmetry reflects structural complexity. Together they help represent how hard a family may remain after known reductions are applied.

4) What is the essential-dimension proxy for?

It acts as a user-supplied structural indicator. When a family requires more independent parameters, the resulting study bound usually increases unless strong reductions are present.

5) What happens if my group is solvable?

The calculator applies a downward adjustment. That reflects the idea that solvable settings often sit closer to classical solution mechanisms than non-solvable symmetry classes.

6) Why can I set custom lower and upper bounds?

Those fields let you blend theory notes with the automatic estimate. They are useful when you already know a published lower bound or a practical upper construction.

7) When should I use the Tschirnhaus option?

Use it when your family has already been normalized or reduced by coordinate changes. That choice slightly lowers the family weight because some complexity has been absorbed.

8) Are the CSV and PDF files suitable for documentation?

Yes. They export the entered inputs, derived metrics, estimated range, and interpretation. That makes the page useful for coursework, research notes, and internal references.
