## ANNOUNCEMENT

**Dear Colleague:**

It is a pleasure to announce that our next workshop ACCOTA'2018, will be held December 2 to 7, 2018 in the peaceful and beautiful city of Merida, Yucatan, Mexico.

As in earlier ACCOTA's, our aim is to bring together mathematicians interested in combinatorics and computing, and their interactions. The Workshop's lectures and contributed papers, as well as the informal mathematical discussions, have proved to be of great interest to participants in previous years. Each discipline represented in the meeting can be of great use in each of the other disciplines, and the purpose of the Workshop is to increase the interaction among researchers in each of the fields represented.

As in ACCOTA'96, ACCOTA'98, ACCOTA'2000, ACCOTA'2002, ACCOTA'2004, ACCOTA'2006, ACCOTA'2008, ACCOTA'2010, ACCOTA'2012, ACCOTA'2014, ACCOTA'2016, workshops, we are expecting internationally recognized mathematicians in the areas of combinatorics and computer science to participate in the workshop this year.

For this Workshop, we hope to count with most of our previous participants, for whom we are asking confirmation: E. Abajo, G. Aguilar, A. Alcantar, P.A. Antonio, G. Araujo, J. Arocha, A. Arroyo, D.

We deeply miss D. Archdeacon(†), A. Bouchet(†), R. Faudree(†), F. Jaeger(†) and V. Neuman-Lara(†).

We are also extending invitations to other colleagues and will notify their participation once confirmed.

The program is planned to include 44 talks. Because of the limited number of time slots, we would greatly appreciate if you would let us know whether or not your intention to participate before **July 15, 2018**. (Please fill in the registration form at http://www.math.cinvestav.mx/accota2018/registration). Participants who wish to give a talk are asked to submit a title and abstract of their talk.

Because of budget restraints in our national scientific programs we can only promise to make our best effort to cover a part of the travel expenses or hotel expenses for exceptional requests. We can only cover a very small number of expense petitions.

The members of the organizing committee are: Gabriela Araujo (IMATE-UNAM), Ruy Fabila (CINVESTAV-IPN), Isidoro Gitler (CINVESTAV-IPN), Sergio Rajsbaum (IMATE-UNAM), Enrique Reyes (CINVESTAV-IPN), Gelasio Salazar (IF-UASLP).

**Sponsors:** Departamento de Matemáticas CINVESTAV-IPN, IMATE-UNAM, SMM and CONACYT-FORDECYT.

A second announcement will be sent in July to all who intend to participate and have let us known so. All relevant information (final program, hotels and reservations, transportation, etc.) will be available at the Internet address http://www.math.cinvestav.mx/accota2018.

We look forward to seeing you in Merida Yucatan, and we hope that you will feel encouraged to attend.
