For four classes of discontinuous functions with unique discontinuous point, we obtain the sufficient and necessary conditions for functions being continuous ones under second iterate, which are ...

Abstract: Brouwer's continuity principle states that all functions from infinite sequences of naturals to naturals are continuous, that is, for every sequence the result depends only on a finite ...

After that, we study its general stability theorem under the conditions that the existence theorem of generalized minimax regret equilibrium point ... functions and feasible constraint mappings are ...

The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) and a maximum turning point when a \(a \textless 0 \). The turning point lies on ...

Abstract: A new nonlinear controller design method based on control Lyapunov functions ... point wise min-norm controller, is presented in this paper, which is a generalized version of Freeman's point ...
