Web12 de fev. de 2024 · Now, desperate times call for beautiful inequalities. Infact, the entirety of PDE theory is littered with inequalities that will blow anyone's mind, from the sublime to the ridiculous. The inequality we use is this one. Recall that for any real a, b we have a2 + b2 ≥ 2ab. We use this to write for any C > 0 : 2ab = 2(a C)(bC) ≤ a2 C2 + C2b2 ...
