we introduce the notions of t-dual rickart and strongly t-dual rickart modules. we provide several characterizations and investigate properties of each of these concepts. it is shown that every free (resp. finitely generated free) $r$-module is t-dual rickart if and only if $overline{z}^2(r)$ is a  direct summand of $r$ and end$(overline{z}^2(r))$ is a semisimple (resp. regular) ring. it is sho...

A bstract The $$ T\overline{T} T ¯ deformation can be formulated as a dynamical change of coordinates. We establish and generalize this relation to curved spaces by coupling the undeformed theory 2d gravity. For space coordinates is supplemented Weyl transformation. a...

Jednym z najważniejszych elementów społecznego trybu życia są zachowania prospołeczne, czyli działania, których korzyści odnoszą inne osobniki. Do najbardziej interesujących podkategorii ryzykownych zachowań prospołecznych należą ratunkowe, spieszenie pomocą osobnikom, które znalazły się w niebezpiecznej sytuacji.
