Similarly, all kinds of parts of mathematics serve as tools for other parts and for other sciences.

This volume contains a selection of papers presented at the 1991 Conrad Conference, held in Gainesville, Florida, USA, in December, 1991. Together, these give an overview of some recent advances in the area of ordered algebraic structures. The first part of the book is devoted to ordered permutation groups and universal, as well as model-theoretic, aspects. The second part deals with material variously connected to general topology and functional analysis. Collectively, the contents of the book demonstrate the wide applicability of order-theoretic methods, and how ordered algebraic structures have connections with many research disciplines.For researchers and graduate students whose work involves ordered algebraic structures.

The conference on Ordered Algebraic Structures held in Curat;ao, from the 26th of June through the 30th of June, 1995, at the Avila Beach Hotel, marked the eighth year of ac­ tivities by the Caribbean Mathematics Foundation (abbr. CMF), which was the principal sponsor of this conference. CMF was inaugurated in 1988 with a conference on Ordered Algebraic Structures. During the years between these two conferences the field has changed sufficiently, both from my point of view and, I believe, that of my co-organizer, W. Charles Holland, to make one wonder about the label "Ordered Algebraic Structures" itself. We recognized this from the start, and right away this conference carried a subtitle, or, if one prefers, an agenda: we concentrated on the one hand, on traditional themes in the theory of ordered groups, including model-theoretic aspects, and, on the other hand, on matters in which topology (more precisely C(X)-style topology) and category theory would play a prominent role. Plainly, ordered algebra has many faces, and it is becoming increas­ ingly difficult to organize an intimate conference, such as the ones encouraged in the series sponsored by CMF, in this area on a broad set of themes. These proceedings reflect, accurately we think, the spirit of the conferees, but it is not a faithful record of the papers presented at the conference.

This publication surveys some of the disciplines within ordered algebraic structures and also contains chapters highlighting a broad spectrum of research interests. In all, this book represents a reasonably accurate cross-section of the state of the art in ordered algebraic structures.

From the 28th of February through the 3rd of March, 2001, the Department of Math­ ematics of the University of Florida hosted a conference on the many aspects of the field of Ordered Algebraic Structures. Officially, the title was "Conference on Lattice­ Ordered Groups and I-Rings", but its subject matter evolved beyond the limitations one might associate with such a label. This volume is officially the proceedings of that conference, although, likewise, it is more accurate to view it as a complement to that event. The conference was the fourth in wh at has turned into aseries of similar conferences, on Ordered Algebraic Structures, held in consecutive years. The first, held at the University of Florida in Spring, 1998, was a modest and informal affair. The fifth is in the final planning stages at this writing, for March 7-9, 2002, at Vanderbilt University. And although these events remain modest and reasonably informal, their scope has broadened, as they have succeeded in attracting mathematicians from other, related fields, as weIl as from more distant lands.

TRES VIDAS EN UNA. Narra la historia de una persona en tres etapas diferentes de su vida, quiz muy distantes una de la otra, pero que las unen muchas cosas entre si (El dolor, el coraje, el amor y las ganas de ver un mundo mejor) Es la historia de un ser, que a pesar de tanta lucha no deja de seguir creyendo que siempre hay un maana mejor, que no importa cual obscuro se encuentre el sendero, siempre ve una luz al final del camino. Desde muy pequeo comenz la lucha por defender su alma al igual que la del, cuerpo, pero desgraciadamente sus fuerzas an eran muy dbiles para defenderse, pero eso no impeda para tener sus propias ilusiones. Sola preguntarse muy a menudo (Siempre hay algo nuevo detrs de cada montaa). Pasan los aos y sigue luchando contra corriente, aunque vea que las puertas se cierran su fe lo impulsa para tomar nuevos impulsos. Es verdad que en muchas situaciones se siente desvanecer por las dificultades por las que atraviesa, pero no importa que tropiece y caiga, lo importante es levantarse y seguir con la mirada hacia el frente. A veces la vida el destino nos tiene reservadas cosas buenas y otras no tan buenas, pero sin embargo eso nos ayuda a saber discernir qu camino debemos tomar para obtener un mejor resultado, aunque como humanos somos imperfectos y nos equivocamos en los caminos de la vida. As pasa en esta historia de vida, un nio, un joven y un adulto, tres vidas que se marcaron desde la infancia, que a veces se siente atrapado, que grita y nadie lo logra escuchar, y sin embargo logra escapar de las garras de la fiera que lo persigue y sigue en busca de algo mejor. Como humanos solemos equivocarnos y de joven nos comemos la luna de un solo bocado, sin medir mucho las consecuencias, pero afortunadamente siempre existe gente buena y de buen corazn que logra sacarnos de nuestros errores y volvernos al camino. Ya siendo un poco ms adultos pensamos que por ser mayores no podemos equivocarnos. Pero la vida se encarga de ponernos en nuestro camino y rectificar lo que hacemos mal.

TRAGEDIA EN SANTA MARIA.Cmo entender el dolor de un hijo ante la prdida del ser que le dio la vida? Cmo mitigar ese dolor? Al pasar los das se incrementa el dolor volvindose intenso cada instante, que no dejas de pensar en aquella terrible noche en que el destino oh la misma maltad se las arrebato de su lado. La misma desgracia que un da los separo a cada uno, ahora por cuestiones del mismo destino los volver a unir para terminar con la maldad que un da los separo. La lucha que han emprendido no ser nada fcil; para eso tienen que quitar todo tipo de rencor que exista en sus corazones, sino! Todo esfuerzo que hagan ser intil! Contando con el apoyo de Ameyal el gran chaman del pueblo. Empezando una gran lucha no sabiendo a qu, o contra quien se enfrentaran, an sin saber el gran poder que tiene esta bestia, ya que no es comn en nuestros tiempos. Solamente ser vencido por el amor de aquella mujer que les dio la vida la cual ellos tanto extraan (su madre adorada). Eso les dar la fuerza para acabar definitivamente con aquella desgracia que un da los separo.

Muchas de las cosas por las que uno lucha en la vida requieren de un absoluto esfuerzo de nuestra parte, por lo tanto son las que ms valoramos an ms. En el amor podemos encontrar esa fuerza que nos impulsa para obtener la felicidad anhelada.

Nunca te imaginarias que para poder ser feliz tendra que morir el que hasta hoy sera tu esposo! Que para ser amada primero tendrs que ser humillada y tu mejor arma ser el amor mismo.

Lo que el 20 se llevó trata sobre el acto de resistir. Aguantarte las ganas de salir, de abrazar a tus seres queridos, de asistir a una fiesta, a un partido de futbol, a un sauna público, a un concierto, a cualquier lugar donde el calor humano reinara.Más que una antología de textos sobre el tema, este libro es una fiesta. Esa reunión que se antojaba imposible antes de que se distribuyera la vacuna. Si piensan que ya se ha escrito todo sobre la pandemia basta asomarse a estas páginas para encontrarse con historias que todavía no habían sido contadas. La música, el cine, el sexo, los meseros, etcétera, conviven aquí sin necesidad de ser sanitizados. Entre la crónica, el ensayo personal y el reporte emocional, los testimonios que el lector tiene entre las manos son un vistazo al mundo interior propiciado por el alineamiento.
