Adaptive Probability Theory: Human Biases as an Adaptation
Humans make mistakes in our decision-making and probability judgments. While the heuristics used for decision-making have been explained as adaptations that are both efficient and fast, the reasons why people deal with probabilities using the reported biases have not been clear. We will see that some of these biases can be understood as heuristics developed to explain a complex world when little information is available. That is, they approximate Bayesian inferences for situations more complex than the ones in laboratory experiments and in this sense might have appeared as an adaptation to those situations. When ideas as uncertainty and limited sample sizes are included in the problem, the correct probabilities are changed to values close to the observed behavior. These ideas will be used to explain the observed weight functions, the violations of coalescing and stochastic dominance reported in the literature
Morse index and multiplicity of min-max minimal hypersurfaces
The Min-max Theory for the area functional, started by Almgren in the early
1960s and greatly improved by Pitts in 1981, was left incomplete because it
gave no Morse index estimate for the min-max minimal hypersurface.
We advance the theory further and prove the first general Morse index bounds
for minimal hypersurfaces produced by it. We also settle the multiplicity
problem for the classical case of one-parameter sweepouts.Comment: Cambridge Journal of Mathematics, 4 (4), 463-511, 201
Newtonian Self-Gravitation in the Neutral Meson System
We derive the effect of the Schr\"odinger--Newton equation, which can be
considered as a non-relativistic limit of classical gravity, for a composite
quantum system in the regime of high energies. Such meson-antimeson systems
exhibit very unique properties, e.g. distinct masses due to strong and
electroweak interactions. We find conceptually different physical scenarios due
to lacking of a clear physical guiding principle which mass is the relevant one
and due to the fact that it is not clear how the flavor wave-function relates
to the spatial wave-function. There seems to be no principal contradiction.
However, a nonlinear extension of the Schr\"odinger equation in this manner
strongly depends on the relation between the flavor wave-function and spatial
wave-function and its particular shape. In opposition to the Continuous
Spontaneous Localization collapse models we find a change in the oscillating
behavior and not in the damping of the flavor oscillation.Comment: 10 pages, no figure
