Abstract
Consider a diagram of quasicategories that admit and functors that preserve limits or colimits of a fixed shape. We show that any weighted limit whose weight is a projective cofibrant simplicial functor is again a quasicategory admitting these (co)limits and that they are preserved by the functors in the limit cone. In particular, the BousfieldKan homotopy limit of a diagram of quasicategories admits any (co)limits existing in and preserved by the functors in that diagram. In previous work, we demonstrated that the quasicategory of algebras for a homotopy coherent monad could be described as a weighted limit of this type, so these results specialise to (co)completeness results for quasicategories of algebras. The second half of this paper establishes a further result in the quasicategorical setting: proving, in analogy with the classical categorical case, that the monadic forgetful functor of the quasicategory of algebras for a homotopy coherent monad creates all limits that exist in the base quasicategory, regardless of whether its functor part preserves those limits. This proof relies upon a more delicate and explicit analysis of the particular weight used to define quasicategories of algebras.
