Abstract
We study various methods for computing the oneloop correction to the energy of classical solutions to type IIA string theory in AdS_4 × CP^3. This involves computing the spectrum of fluctuations and then adding up the fluctuation frequencies. We focus on two classical solutions with support in CP^3: a rotating pointparticle and a circular spinning string with two angular momenta equal to J. For each of these solutions, we compute the spectrum of fluctuations using two techniques, known as the algebraic curve approach and the worldsheet approach. If we use the same prescription for adding fluctuation frequencies that was used for type IIB string theory in AdS_5 × S^5, then we find that the worldsheet spectrum gives convergent oneloop corrections but the algebraic curve spectrum gives divergent ones. On the other hand, we find a new summation prescription which gives finite results when applied to both the algebraic curve and worldsheet spectra. Naively, this gives three predictions for the oneloop correction to the spinning string energy (one from the algebraic curve and two from the worldsheet), however we find that in the large  J limit (where J = J /√2π^2⋋),J^(2n) terms in all three cases agree. We therefore obtain a unique prediction for the oneloop correction to the spinning string energy.
