In mathematics, a lattice is a discrete subgroup of the complex plane that can be generated by two linearly independent complex numbers, often represented as points in a two-dimensional space. Lattices are crucial in the study of complex tori, as they provide a way to construct these tori by identifying points in the complex plane with equivalent classes. This connection between lattices and complex tori also leads to the understanding of elliptic curves through their representation as quotients of the complex plane by a lattice.
congrats on reading the definition of Lattice. now let's actually learn it.
