A radical theory for graphs that do not admit loops
Periodica Mathematica Hungarica, 2022 AbstractThere is a well-developed theory of connectednesses and disconnectednesses (= radical theory) for the category of graphs that admit loops. Here it is shown that such a theory for the category of graphs that do not allow loops degenerates to the trivial case for all the Hoehnke radicals, but there are non-trivial connectednesses (KA-radical ...

Modular graph functions and odd cuspidal functions. Fourier and Poincaré series
Journal of High Energy Physics, 2019 Modular graph functions are SL(2, ℤ)-invariant functions associated with Feynman graphs of a two-dimensional conformal field theory on a torus of modulus τ. For one-loop graphs they reduce to real analytic Eisenstein series. We obtain the Fourier series,

Ladder and zig-zag Feynman diagrams, operator formalism and conformal triangles
Journal of High Energy Physics, 2023 We develop an operator approach to the evaluation of multiple integrals for multiloop Feynman massless diagrams. A commutative family of graph building operators H α for ladder diagrams is constructed and investigated.

Design of Strict Control-Lyapunov Functions for Quantum Systems with QND Measurements [PDF]
, 2011 We consider discrete-time quantum systems subject to Quantum Non-Demolition (QND) measurements and controlled by an adjustable unitary evolution between two successive QND measures.

Knot Invariants and New Weight Systems from General 3D TFTs [PDF]
, 2011 We introduce and study the Wilson loops in a general 3D topological field theories (TFTs), and show that the expectation value of Wilson loops also gives knot invariants as in Chern-Simons theory.

Extracting Einstein from the loop-level double-copy
Journal of High Energy Physics, 2021 The naive double-copy of (multi) loop amplitudes involving massive matter coupled to gauge theories will generically produce amplitudes in a gravitational theory that contains additional contributions from propagating antisymmetric tensor and dilaton ...

Applications oriented input design for closed-loop system identification: a graph-theory approach
53rd IEEE Conference on Decision and Control, 2014 A new approach to experimental design for identification of closed-loop models is presented. The method considers the design of an experiment by minimizing experimental cost, subject to probabilistic bounds on the input and output signals, and quality constraints on the identified model.
