Mathematical Semiotic Modeling: 45-Week Parabola Function on Example Four Cases of Global Crisis
Year: 2026
Type: preprint
Abstract: This research is a Mathematical Semiotic Modeling that tests a 45-week calendar pattern using the parabola function f(x) = -x² + 45x + 1/4. This function was published earlier in November 2025 through YouTube Publication: International Paper RESEARCH II, before the tested events occurred in 2026. The axis of symmetry is at x = 22.5, calibrated to 3 June 2026. The peak value is f(22.5) = 506.5 and the value at the adjacent point is f(23) = 506.25. The four cases tested in this journal are only a few example cases, namely 1) 33 Countries Told to Stock Food, 2) The Fed 0.25, 3) Indonesian Exchange Rate, and 4) Microsoft Layoff of 4,800, showing the same pattern: first peak on 3 June 2026, and second execution on 24 June 2026, i.e. 3 June + 506.5 hours = 21.1 days. Keywords: 45 weeks, axis of symmetry, 3 June 2026, 506.5, 24 June 2026
