Abstract. An introduction to the global (infrared) completion of Maxwell-type higher gauge fields (as in the higher gauge sectors of higher-dimensional supergravity and its super $p$-branes) by electromagnetic flux quantization in differential nonabelian cohomology, using methods of cohesive homotopy theory. Examples include D/NS brane charge in (unstable) K-theory, M-brane charge in unstable Cohomotopy and geometric engineering of topological quantum order on probe M5-branes.

Based on:

• Flux Quantization

• Flux Quantization on Phase Space

• Flux Quantization on 11D Superspace

• Flux Quantization on M5-Branes

• Flux Quantization on M-Strings

• Flux Quantization of Type IIA

• Complete Topological Quantization of Higher Gauge Fields

• The Character Map in Non-Abelian Cohomology
