Abstract
We construct four series of modular categories from the two-variable Kauffman polynomial, without use of the representation theory of quantum groups at roots of unity. The specializations of this polynomial corresponding to quantum groups of types B, C and D produce series of pre-modular categories. One of them turns out to be modular and three others satisfy Bruguières’ modularization criterion. For these four series we compute the Verlinde formulas, and discuss spin and cohomological refinements.
