Articles in this volume are based on presentations given at the IV Meeting of Mexican Mathematicians Abroad (IV Reunion de Matematicos Mexicanos en el Mundo), held from June 10-15, 2018, at Casa Matematica Oaxaca (CMO), Mexico. This meeting was the fourth in a series of ongoing biannual meetings bringing together Mexican mathematicians working abroad with their peers in Mexico. This book features surveys and research articles from five broad research areas: algebra, analysis, combinatorics, geometry, and topology. Their topics range from general relativity and mathematical physics to interactions between logic and ergodic theory. Several articles provide a panoramic view of the fields and problems on which the authors are currently working on, showcasing diverse research lines complementary to those currently pursued in Mexico. The research-oriented manuscripts provide either alternative approaches to well-known problems or new advances in active research fields. This book is published in cooperation with Sociedad Matematica Mexicana.

Everything there is to know about avocados is here: ancient origins, amazing health properties, restorative cosmetic uses, and a recipe collection far beyond the tried and true. This book features a fresh visual design aesthetic that reflects the creative sensibility of Mexican contemporary art, graphic design, atmospheric photography, and street style. Recipes cover everything from guacamole in many variations, salads, unusual sides, many permutations of avocado toast even toastless avocado sandwiches as well as less well-known and offbeat uses. The book also explores avocado butter and oil; detoxifying smoothies; rejuvenating cosmetic salves and masks, and much more. Practical matters are also addressed: an avocado overview by type; storage tips; preserving the brilliant green flesh from browning; ripening immature fruits; and safety tips for slicing and de-pitting. Avocados are grown in Mediterranean climates globally and dominate social media, hip restaurant menus, and health-based diets, but this is the first book paying tribute to the superfruit s deep roots as a native, Mexican heritage food.

Quartic anharmonic oscillator with potential V(x)= x(2) + g(2)x4 was the first non-exactly-solvable problem tackled by the newly-written Schroedinger equation in 1926. Since that time thousands of articles have been published on the subject, mostly about the domain of small g(2) (weak coupling regime), although physics corresponds to g(2) ~ 1, and they were mostly about energies.This book is focused on studying eigenfunctions as a primary object for any g(2). Perturbation theory in g(2) for the logarithm of the wavefunction is matched to the true semiclassical expansion in powers of : it leads to locally-highly-accurate, uniform approximation valid for any g(2) [0, ) for eigenfunctions and even more accurate results for eigenvalues. This method of matching can be easily extended to the general anharmonic oscillator as well as to the radial oscillators. Quartic, sextic and cubic (for radial case) oscillators are considered in detail as well as quartic double-well potential.
