It is known that not all summation methods are linear and stable. Zeta function regularization is in general nonlinear. However, in some cases formal manipulations with zeta function regularization (assuming linearity of sums) lead to correct results. We consider several examples and show why this happens. 
Free energy on a cycle graph and trigonometric deformation of heat kernel traces on odd spheres
We consider a possible ‘deformation’ of the trace of the heat kernel on odd dimensional spheres, motivated by the calculation of the free energy of a scalar field on a discretized circle. By using an

We argue that the conjectural relation between the subleading term in the small-squashing expansion of the free energy of general three-dimensional CFTs on squashed spheres and the stress-tensor

Large charge at large N
Abstract We apply the large-charge expansion to O(N) vector models starting from first principles, focusing on the Wilson-Fisher point in three dimensions. We compute conformal dimensions at zero

Resurgence of the large-charge expansion
Abstract We study the O(2N) model at criticality in three dimensions in the double scaling limit of large N and large charge. We show that the large-charge expansion is an asymptotic series, and we

A matrix CFT at multiple large charges
A bstractWe investigate matrix models in three dimensions where the global SU(N ) symmetry acts via the adjoint map. Analyzing their ground state which is homogeneous in space and can carry either a
Free energy and defect $C$-theorem in free scalar theory
We describe conformal defects of $p$ dimensions in a free scalar theory on a $d$-dimensional flat space as boundary conditions on the conformally flat space $\mathbb{H}^{p+1}\times

The Casimir energy for the transverse oscillations of a piecewise uniform closed string is calculated and delicate points in the regularization procedure are discussed; it turns out that a straightforward use of the Riemann {zeta}-function regularization method leads to an incorrect expression for the CasimirEnergy.
