چکیده

In this paper x, a are real numbers. Next we state a number of propositions: (1) If a ­ 0 and (x − a) · (x + a) ­ 0, then −a ­ x or x ­ a. (2) If a ¬ 0 and x < a, then x > a. (3) For every point p of E2 T such that |p| ¬ 1 holds −1 ¬ p1 and p1 ¬ 1 and −1 ¬ p2 and p2 ¬ 1. (4) For every point p of E2 T such that |p| ¬ 1 and p1 6= 0 and p2 6= 0 holds −1 < p1 and p1 < 1 and −1 < p2 and p2 < 1. (5) Let a, b, d, e, r3 be real numbers, P1, P2 be non empty metric structures, x be an element of the carrier of P1, and x2 be an element of the carrier of P2. Suppose d ¬ a and a ¬ b and b ¬ e and P1 = [a, b]M and P2 = [d, e]M and x = x2 and x ∈ the carrier of P1 and x2 ∈ the carrier of P2. Then Ball(x, r3) ⊆ Ball(x2, r3).

One can prove the following propositions: (2) For all real numbers a, b, r such that 0 ¬ r and r ¬ 1 and a ¬ b holds a ¬ (1 − r) · a + r · b and (1 − r) · a + r · b ¬ b. (3) For all real numbers a, b such that a ­ 0 and b > 0 or a > 0 and b ­ 0 holds a + b > 0. (4) For all real numbers a, b such that −1 ¬ a and a ¬ 1 and −1 ¬ b and b ¬ 1 holds a · b ¬ 1. (5) For all real numbers a, b such that ...

On the Simple Closed Curve Property of the Circle and the Fashoda Meet Theorem for It

First, we prove the fact that the circle is the simple closed curve, which was defined as a curve homeomorphic to the square. For this proof, we introduce a mapping which is a homeomorphism from 2-dimensional plane to itself. This mapping maps the square to the circle. Secondly, we prove the Fashoda meet theorem for the circle using this homeomorphism. In this paper x, y, z, u, a are real numbe...

Graph Theoretical Properties of Arcs in the Plane and Fashoda Meet Theorem

We define a graph on an abstract set, edges of which are pairs of any two elements. For any finite sequence of a plane, we give a definition of nodic, which means that edges by a finite sequence are crossed only at terminals. If the first point and the last point of a finite sequence differs, simpleness as a chain and nodic condition imply unfoldedness and s.n.c. condition. We generalize Goboar...

On the Simple Closed Curve Property of the Circle and the Fashoda Meet Theorem

In this paper x, y, z, u, a are real numbers. We now state a number of propositions: (1) If x = y, then x = y or x = −y. (2) If x = 1, then x = 1 or x = −1. (3) If 0 ¬ x and x ¬ 1, then x ¬ x. (4) If a ­ 0 and (x − a) · (x + a) ¬ 0, then −a ¬ x and x ¬ a. (5) If x − 1 ¬ 0, then −1 ¬ x and x ¬ 1. (6) x < y and x < z iff x < min(y, z). (7) If 0 < x, then x3 < x and x 4 < x. (8) If x ­ 1, then √x ...

Determination of Gain and Phase Margins in Lur’e Nonlinear Systems using Extended Circle Criterion

Nonlinearity is one of the main behaviors of systems in the real world. Therefore, it seems necessary to introduce a method to determine the stability margin of these systems. Although the gain and phase margins are established criteria for the analysis of linear systems, finding a specific way to determine the true value of these margins in nonlinear systems in general is an ongoing research i...
