 5 Vector space of polynomials over $\mathbb{R}$ with degree $\leqslant n-1$ 5 Determinants of block matrices 2 A linear operator is continuous if and only if it maps cauchy sequences to cauchy sequences 1 Group of conjugation mappings isomorphic to original group 1 T, U, W are vector subspaces of V. If $T \subset W, U \cap W = U \cap T$ and $U + W = U + T$ then $T=W$.
