research

I am doing research in mathematical fundamental physics (e.g. on Hypothesis H and TQC in TED-K).

For latest talk notes see here.

research wiki

I like to put math/phys information into context.
For that purpose I had started (in Nov 2008)

• the $n$Lab research wiki project

with edit logs and discussion being had on:

• the nForum discussion board.

For more on the $n$Lab, see:

• me on: What is… the nLab?

  (presentation at Big Data in Pure Mathematics 2022)

• Wikipedia on: nLab.

more web logs

For logs of further activity see my page

• at Twitter

while $n$Lab-edits are announced

• on the $n$Forum.

For links to technical discussions about math and physics see my pages:

• at MathOverflow

• at PhysicsOverflow

• at Physics.SE

• at QuantumComputing.SE.

• Examples of Prequantum field theories III: Chern-Simons-type theories

• Examples of Prequantum field theories IV: Wess-Zumino-Witten-type theories

on perturbative quantum field theory

• Introduction to Perturbative Quantum Field Theory

on string theory

• It was 20 years ago today – the M-theory conjecture

• Homotopy Lie n-algebras in Supergravity

• Emergence from the superpoint

• Why supersymmetry? Because of Deligne’s theorem

• 11d Gravity from just the Torsion Constraint

• Spectral Standard Model and String Compactifications

• Why Higher Category Theory in Physics?

• Super p-Brane Theory from Super Homotopy Theory
