Polish algebras, shy from freedom

Polish Algebras, Shy from Freedom Sh771

Every Polish group is not free whereas some Fσ group may be free. Also every automorphism group of a structure of cardinality, e.g. iω is not free. This research was partially supported by the Israel Science Foundation. Publication 771 I would like to thank Alice Leonhardt for the beautiful typing.

Do Women Shy Away from Competition?

Competitive high ranking positions are largely occupied by men, and women remain scarce in engineering and sciences. Explanations for these occupational differences focus on discrimination and preferences for work hours and field of study. We explore an additional explanation, namely that women and men may differ in their selection into competitive environments. Men and women in a laboratory ex...

Module homomorphisms from Frechet algebras

We first study some properties‎ ‎of $A$-module homomorphisms $theta:Xrightarrow Y$‎, ‎where $X$‎ ‎and $Y$ are Fréchet $A$-modules and $A$ is a unital‎ ‎Fréchet algebra‎. ‎Then we show that if there exists a‎ ‎continued bisection of the identity for $A$‎, ‎then $theta$ is‎ ‎automatically continuous under certain condition on $X$‎. ‎In‎ ‎particular‎, ‎every homomorphism from $A$ into certain‎ ‎Fr...

Aggressive, Tense or Shy? Identifying Personality Traits from Crowd Videos

We present a real-time algorithm to automatically classify the dynamic behavior or personality of a pedestrian based on his or her movements in a crowd video. Our classification criterion is based on Personality Trait Theory. We present a statistical scheme that dynamically learns the behavior of every pedestrian in a scene and computes that pedestrian’s motion model. This model is combined wit...
