👉 In mathematics, a weigela (also known as a Weierstrass function) is a type of complex-valued polynomial that has an interesting property. When this polynomial is evaluated at certain points, it produces a sequence of numbers that are all equal to each other. This property is called the "Weierstrass condition" and was first introduced by Hermann Weyl in his work on modular forms. The function is named after Karl Weierstrass, who discovered it independently
