Some applications of topological horseshoes to chaos

Lakshmi Burra

IIIT Hyderabad

We present a few applications of the theory of “topological horseshoes” to give a rigorous proof of the presence of chaotic dynamics in some nonlinear ordinary differential equations with periodic perturbations. Our results, although dealing with planar Hamiltonian systems, are stable for small perturbations and we can allow the presence of a damping coefficient as [...]

A new view of space time

prof. B. G. Sidharth

Founder Director General B.M.Birla Science Centre, Adarshnagar, Hyderabad (India), Advisor and Prof. Theoretical Physics, Santa Rita Univ. Florence, Italy

Einstein‘s geometry of special relativity was based on the Michaelson Morley experiment. This leads to the imposition of a maximal velocity which was a huge departure from Newtonian mechanics in which infinite velocity is possible. Then came the various science fiction effects like time dilatation, space contraction and so on. We adopt a different [...]

Per una matematica accessibile e inclusiva: il LaTeX come soluzione al problema dell’accesso a testi con formule da parte di disabili visivi

Anna Capietto / Cristian Bernareggi

Università di Torino

Il gruppo di ricercatori dell’Università di Torino, guidato dalla Prof.ssa Anna Capietto ha messo a punto un sistema per realizzare in maniera automatizzata testi scientifici in formato digitale accessibili, mediante apposite tecnologie assistive, da persone con disabilità visiva. Nell'ambito di LaTeX i ricercatori hanno realizzato un pacchetto aggiuntivo che permette agli autori di rendere accessibili i [...]

An introduction to option pricing

Ariel Aldo Giovanni Lanza

Corso di Laurea Magistrale in Matematica

Financial options are contracts that grant the right, but not the obligation to buy or sell an underlying asset at a set price on or before a certain date. The “right” price at which an option should be sold is a major topic in financial mathematics. In this seminar the problem is faced from several [...]

Coarse Proximity and Proximity at Infinity

Pawel Grzegrzolka

University of Tennessee, Knoxville, TN, USA

Coarse topology (i.e., large scale geometry) is a branch of mathematics investigating large-scale properties of spaces. While classical topology is primarily concerned with what happens "on the small-scale" (e.g., limits, continuity), coarse topology focus predominantly on what happens "on the large-scale" (e.g., asymptotic dimension, coarse equivalence of spaces). The idea of “translating” a small-scale world to [...]
