symmetric monoidal (infinity,1)-category
With duals for objects
With duals for morphisms
Special sorts of products
In higher category theory
A symmetric monoidal -category is
This means that it is
This can be understood as a special case of an (∞,1)-operad (…to be expanded on…)
Definition in terms of quasi-categories
Recall that in terms of quasi-categories a general monoidal (infinity,1)-category is conceived as a coCartesian fibration of simplicial sets over the (opposite of) the nerve of the simplex category satisfying a certain property.
The fiber of this fibration over the 1-simplex is the monoidal (infinity,1)-category itself, its value over a map encodes the tensor product of factors of with itself.
The following definition encodes the commutativity of all these operations by replacing with the category of pointed finite sets.
A symmetric monoidal -category is a coCartesian fibration of simplicial sets
- for each the associated functors determine an equivalence of -categories .
See (Lurie, def. 184.108.40.206).

Model category structure
A presentation of the (∞,1)-category of all symmetric monoidal -categories is provided by the model structure for dendroidal coCartesian fibrations.
