  1. 23. Mai 2024 · Sei \(A\in \mathbb {C}^{n,n}\) mit n paarweise verschiedenen Eigenwerten und seien \(R_1,R_2\in \mathbb {C}^{n,n}\) zwei Schur-Formen von A. Sind die Diagonalen von \(R_1\) und \(R_2\) gleich, dann gilt \(R_1={QR_2Q^H}\) für eine unitäre Diagonalmatrix Q .

  2. 7. Mai 2024 · UC Riverside. Symmetric groups, Schur algebras and Hilbert schemes. Abstract: In his 1901 thesis, Issai Schur discovered a connection between the representation theory of the symmetric group and general linear group. One way to understand this connection is through a finite dimensional algebra called the Schur algebra.

  3. Vor 5 Tagen · As of the 20th century, groups gained wide recognition by the pioneering work of Ferdinand Georg Frobenius and William Burnside (who worked on representation theory of finite groups), Richard Brauer's modular representation theory and Issai Schur's papers.

  4. 14. Mai 2024 · Issai Schur ( 1917) independently rediscovered and proved the identities. Definition. The Rogers–Ramanujan identities are. (sequence A003114 in the OEIS) and. (sequence A003106 in the OEIS ). Here, denotes the q-Pochhammer symbol . Combinatorial interpretation. Consider the following:

  5. Vor 3 Tagen · Theorem 1: Let A be an m × n matrix. (Overdetermined case) If m > n, then the linear system Ax =b is inconsistent for at least one vector b in Rn. (Undetermined case) If m < n, then for each vector b in Rm the linear system Ax =b is either inconsistent or has infinite many solutions.
