Economists are interested in examining types of relationships. For example an economist may look at the amount of money a person earns and the amount that person chooses to spend. This is a ...

We consider integrals on unitary groups Ud of the form ∫ UdUi1 j1···Uiq jqUj′1i′1∗···Uj′q′i′q′∗dU⁠. We give an explicit formula in terms of characters of symmetric groups and Schur functions, which ...

Abstract: Estimation of higher-order state variables such as velocity and acceleration requires high accuracy and wide bandwidth in position measurement in motion control. The purpose of this study is ...

We present integer linear models with a polynomial number of variables and constraints for combinatorial optimization problems in graphs: optimum elementary cycles, optimum elementary paths and ...
