Question

what does geometric representation mean?

Answer 1

${}\huge{\bold{\pink{heya.....}}}$


A Geometrical Representation. It turns out that the previous case, scattering by a one-dimensional chain, can be visualised by means of a geometrical figure known as the Ewald sphere (or sphere of reflection) plus the reciprocal lattice.

Answer 2

Geometric representation theory studies representations (of various symmetry objects like algebraic groups, Hecke algebras, quantum groups, quivers etc.) realizing them bygeometric means, e.g. by geometrically defined actions on sections of various bundles or sheaves as in geometric quantization
