In mathematics, the determinant of a skew-symmetric matrix can always be written as the square of a polynomial in the matrix entries, a polynomial with integer coefficients that only depend on the size of the matrix. The value of this polynomial, when applied to the coefficients of a skew-symmetric matrix, is called the Pfaffian … Se mer $${\displaystyle A={\begin{bmatrix}0&a\\-a&0\end{bmatrix}}.\qquad \operatorname {pf} (A)=a.}$$ (3 is odd, so the Pfaffian of B is 0) Se mer Pfaffians have the following properties, which are similar to those of determinants. • Multiplication of a row and a column by a constant is equivalent to multiplication of the Pfaffian by the … Se mer • There exist programs for the numerical computation of the Pfaffian on various platforms (Python, Matlab, Mathematica) (Wimmer 2012).

Nettet14. feb. 2024 · 1 Introduction. The aim of this paper is to present a formula for Schur’s Q -functions under the action of the Virasoro operators. Schur’s Q -function is a Pfaffian of an alternating matrix. First we recall the Pfaffians. Let A= (a_ {ij})_ {1\le i,j \le 2m} be an alternating 2m\times 2m matrix. The Pfaffian of A is by definition, Nettet4. nov. 2024 · Here we use the density-matrix renormalization-group (DMRG) method to study the Hofstadter-Bose-Hubbard model at filling factor and find strong indications that at magnetic flux quanta per plaquette the ground state is a lattice analog of the continuum non-Abelian Pfaffian.
