22: 212:, which generically writes a matrix as the product of an upper triangular matrix with a lower triangular matrix—but with exceptional cases. It is related to the Schubert cell decomposition of 158:. Since the use of Lie group methods became one of the standard techniques in twentieth century mathematics, many phenomena can now be referred back to decompositions. 43: 266: 179: 94: 113: 66: 73: 47: 209: 80: 62: 197: 32: 273: 262: 51: 36: 351: 321: 303: 235: 143: 325: 314: 299: 224: 186: 87: 346: 295: 291: 151: 258: 228: 155: 313:
