2011/2/28
We formulate the problem of renormalization of Feynman integrals and its relation to periods of motives in configuration space instead of momentum space.
The Feynman checkerboard problem is an interesting path integral approach to the Dirac equation in ‘1+1’ dimensions. I compare two approaches reported in the literature and show how they may be reconc...

Feynman's Tree Theorem Loop-Tree Dualities
2010/12/24
We discuss the duality theorem, which provides a relation between loop integrals and phase space integrals. We rederive the duality relation for the one-loop case and extend it to two and higher-order...
The classical notions of continuity and mechanical causality are left in order to refor- mulate the Quantum Theory starting from two principles: I) the intrinsic randomness of quantum process at micr...
