The most common method to find the vertex from the standard form involves using the vertex formula: k = f (h) (Substitute the ...

A quadratic function is a polynomial equation of degree two which typically takes the form of y = ax^2 + bx + c, where a, b, and c are constants. The vertex of a quadratic function is the point that ...

Abstract: We study graded traces of vectors in free bosonic vertex operator algebras and lattice vertex operator algebras. We show in particular that trace functions in these two theories always have ...
