ABSTRACT: The N-representability conditions on the reduced second-order reduced density matrix (2-RDM), impose restrictions not only in the context of reduced density matrix theory (RDMT), but also on ...

ABSTRACT: A double system of exponents with piecewise continuous complex-valued coefficients are considered. Under definite conditions on the coefficients the frame property of this system in Lebesgue ...

Exponential and logarithmic functions are typically presented as formulas with which students learn to associate the rules for exponents/logarithms, a particular algebraic form, and routine algorithms ...

Abstract: The problem of nonlinear system modeling consists of searching for an operator which transforms a class of source effects in the target class. Having a series of test signals and their ...

Abstract: Most texts dealing with this subject assume that the reader is familiar with complex exponential functions. They also omit steps in mathematical transformations on the assumption that the ...

There is a bug in se3_exp_map and/or se3_log_map ( I think likely the latter) as there are some transformations that applying the log operation and then the exponential, that exponential is off by a ...
