On Spinning Particles, their Partition Functions and Picture Changing Operators
Eugenia Boffo, Pietro Antonio Grassi, OndÅej HulÃk +1
We compute the partition function for the spinning particle, including pictures and the large Hilbert space, and show that it counts the dimension of the BRST cohomology in t…

Local Operator Algebras of Charged States in Gauge Theory and Gravity
Pietro Antonio Grassi, Massimo Porrati
Powerful techniques have been developed in quantum field theory that employ algebras of local operators, yet local operators cannot create physical charged states in gauge theory o…

BV Formalism and Partition Functions
Pietro Antonio Grassi, Ondrej Hulik
The BV formalism is a well-established method for analyzing symmetries and quantization of field theories. In this paper we use the BV formalism to derive partition functions of ga…
