Constructed Websites

A compact directory for the browser-side mathematical tools in this folder. Each entry has a GIF preview slot and a direct link to the working page.

Partitions

Draw a partition by cells and read off hooks, conjugates, tableaux counts, weights, and related data.

Add gif/double_young_diagram_gif_1.gif

Representation Theory

Work with pairs of partitions, tensor products, Littlewood-Richardson data, and fixed-rank Lie types.

Add gif/higher_dimensional_slice_explorer_gif_1.gif

Higher-Dimensional Geometry

Move an affine frame through regular polytopes, spheres, Cartesian frames, and points; compare projection with exact 2D slices.

Add gif/mosaic_calculator_gif_1.gif

Knots, Links, and Surfaces

Build hexagonal or square mosaics for knots, links, dual graphs, and glued background surfaces; inspect invariants, cusps, and surface types.

Add gif/matrix_calculator_gif_1.gif

Linear Algebra

Edit matrices and compute standard linear algebra outputs inside the shared applet interface.

Open calculator
Add gif/sheaf_calculator_gif_1.gif

Algebraic Geometry

Assemble varieties, maps, and sheaves, then compute characteristic classes and pushforward-style data.

Open calculator
Add gif/dynkin_diagram_calculator_gif_1.gif

Lie Theory

Switch between classical and exceptional Dynkin types and inspect their diagram and root-system data.

Prototypes

Prototype Websites

Early versions kept for future development. These pages may be incomplete, rough, or missing demonstration media.

Mathematics

Sketch categories, opposite categories, symbolic morphism templates, and covariant or contravariant functors.

Open prototype

Mathematics

Build a dependency graph of theorem, lemma, conjecture, and reference nodes.

Open prototype

Algebraic Geometry

Strengthen the sheaf calculator with editable LaTeX chain complexes and filtrations.

Open prototype

Number Theory

Explore how rational primes split or ramify in selected number-field examples.

Open prototype

Symmetric Groups

Build adjacent-transposition strand diagrams and compare word, cycle, one-line, matrix, and export forms.

Open prototype

Games

Play small surface-aware games, beginning with a glued-boundary 2048 variant.

References Followed Directly

The applets here were not designed in isolation. These are the websites I used most directly as models or mathematical references when asking AI to help construct the pages.

Young Diagram Calculator

The single Young diagram calculator follows this original combinatorics applet most directly.

Young Diagram2, Higher-Dimensional Slices, and Dynkin Diagram

Lievis guided the two-dimensional slice visualization in the double Young diagram calculator, informed the Higher-Dimensional Slice Calculator, and also influenced the Dynkin diagram calculator.

Open Lievis

Mosaic Calculator Archive

Hexapipes suggested the main canvas interaction, KnotFolio suggested the idea of identifying drawn knots, and KnotInfo supplied knot naming conventions and database context.

Sheaf Calculator

Pieter Belmans' cohomology tables were a direct reference for the sheaf calculator's algebraic geometry viewpoint.

Open cohomology tables

Theorem Graph Calculator

The arrow type controls and endpoint vocabulary in the theorem graph calculator learned a lot from q.uiver's diagram editor.

Open q.uiver

Place Ramification Calculator

LMFDB's database style and number-theory organization were a direct reference for the place ramification calculator.

Open LMFDB beta

A larger collection of databases, atlases, and mathematical web tools is kept in the recommendation page.
