We look at various uniform and non-uniform complexity classes within P=poly and its variations L=poly, NL=poly, NP=poly and PSpace=poly, and look for analogues of the Ajtai-Immerman theorem which characterizes AC0 as the non-uniformly First Order Definable classes of finite structures. how to set up shaw email account in outlookWitryna6 paź 2024 · In this paper we give an Immerman Theorem for real-valued computation, i.e., we define circuits of unbounded fan-in operating over real numbers and show that families of such circuits of polynomial size and constant depth decide exactly those sets of vectors of reals that can be defined in first-order logic on \mathbb {R} -structures in … how to set up shark robot vacuum

In quantum field theory, the LSZ reduction formula is a method to calculate S -matrix elements (the scattering amplitudes) from the time-ordered correlation functions of a quantum field theory. It is a step of the path that starts from the Lagrangian of some quantum field theory and leads to prediction of measurable quantities.

An important issue in circuit complexity is uniformity, i.e., the question if a ﬁnite description of an inﬁnite family of circuits exists, and if yes, how complicated it is to obtain it. Immerman’s Theorem holds both non-uniformly, i.e., under no requirements on the constructability of the circuit family, as well nothing pose nothing pressing meaning
