# Blob algebra and two-color Soergel calculus

## TL;DR

This paper explores a potential conceptual link between the blob algebra's representation theory and two-color Soergel calculus, proposing a conjecture that connects endomorphism algebras of Bott--Samelson bimodules to blob algebra subalgebras, supported by evidence.

## Contribution

It introduces a conjecture relating Bott--Samelson bimodule endomorphisms to blob algebra subalgebras, offering a new perspective on their connection.

## Key findings

- Evidence supports the proposed conjecture.
- A new algebraic relationship is suggested.
- Potential implications for representation theory.

## Abstract

In 2003, Martin and Woodcock noticed a connection between the representation theory of the blob algebra and the Kazhdan--Lusztig polynomials associated with the infinite dihedral group. However, no conceptual explanation for this coincidence has yet been provided. In this study, a possible explanation of this phenomenon is suggested by enunciating a conjecture that relates the endomorphism algebra of Bott--Samelson bimodules to certain subalgebras of the blob algebra obtained by idempotent truncation. Evidence supporting this conjecture is provided.
