WebThe probability of each final state is then obtained by summing over all such possibilities. This is closely tied to the functional integral formulation of quantum mechanics, also invented by Feynman—see path integral formulation . Web18 Sep 2024 · 1. In short, the number of lattice points of given bounded magnitude grows linearly, giving a contribution proportional to n ⋅ 1 n 2 = 1 n, making the series diverge. I give a proof that ∑ ω ∈ Λ ∗ ω − s converges absolutely iff s > 2: Fix a lattice Λ ∈ C and set Ω r = { m λ 1 + n λ 2 m, n ∈ Z and max ( m , n ) = r }.
