Abstract
In this last chapter, we address for determinantal ideals \( I \subset K\left[ {x_0 , \ldots x_n } \right] \), i.e., ideals of codimension c = (p - r + 1)(q - r + 1) generated by the r × r minors of a p × q homogeneous matrix A (see Definition 1.2.3), for symmetric determinantal ideals \( I \subset K\left[ {x_0 , \ldots x_n } \right] \), i.e., ideals of codimension \( c = \left( {\begin{array}{*{20}c} {m - t + 2} \\ 2 \\ \end{array} } \right) \) generated by the t × t minors of an m × m homogeneous symmetric matrix A (see Definition 1.2.5), and for the three problems considered in the previous chapters for standard determinantal ideals. Namely, we address the following problems:
-
(1)
CI-liaison class and G-liaison class of determinantal ideals,
-
(1′)
CI-liaison class and G-liaison class of symmetric determinantal ideals,
-
(2)
the multiplicity conjecture for determinantal ideals,
-
(2′)
the multiplicity conjecture for symmetric determinantal ideals,
-
(3)
unobstructedness and dimension of families of determinantal schemes, and
-
(3′)
unobstructedness and dimension of families of symmetric determinantal schemes
