f(x+xy+f(y)) =\left(f(x)+\frac{1}{2}\right)\left(f(y)+\frac{1}{2}\right)

(1,k^2+1),(k^2+1,1)

\sum\limits_{n = 1}^{34} {(n^2 + 2n + 1)}

\sin ^2 \theta + cos ^2 \theta = 1

\min_\gamma \text{s.t.}\ P > 0 \ \begin{bmatrix}-P & A^TP & A^TP & H^T \\ PA & P-I & 0 & 0 \\ PA & 0 & -P & 0 \\ H & 0 & 0 & -\gamma I\end{bmatrix}<0

1 \oplus 2 = 9
