Li-convex set

Where mathematics finds its place, There exists a series, oh so grand, Called the convex series, let's understand. x1, x2, and so on, until we're done, These elements reside in a space, A topological vector, a special place. The coefficients, r1, r2, they prevail, Non-negative numbers, they must be, And when added together, they sum to one, you see. And then added up, all the way to the unknown, The convex series, it takes its form, A sum of products, a mathematical norm. In the realm of numbers, where wonders shine, The convex series, a mathematical treasure, Bringing joy and knowledge, beyond measure. Random page: UTC-02
