Semigroups and combinatorial applications / Gerard Lallement.

[Longhorn Review] Semigroups and combinatorial applications / Gerard Lallement.

Material Type: All, Books — Posted on December 10, 2013, 9:57 am

By: Retired Professor

The book starts on p.1 with Definition 1.1, of nine lines, in which are mixed six definitions and one theorem: 1. semigroup, 2. identity, 3. zero, 4. right zero but not left zero, 5. idempotent, and 6. commutative; the interlineated theorem states but does not prove uniqueness of an identity or a zero. Certainly not well written. Then on p.3, two different notations for the smallest subsemigroup containing A. Perhaps the Combinatorial Applications are better.

Exactly as reviewed previously. A quick and dirty analysis of various government information/press strategies employed during Vietnam and WWII. Specifically, it analyzes how the government organized various information departments during WWII and the government's failure to organize departments and strategies during Vietnam. Ultimately, why these oversights contributed to Vietnam's strategic failures.

Lectures in abstract algebra.

[Longhorn Review] Lectures in abstract algebra. vol 1, Nathan Jacobson

Material Type: All, Books — Tags: identity element, partial order, unit element — Posted on April 26, 2013, 10:37 am

By:

p.188 a partial order is asymmetric and transitive, but in
J.M.Howie, Fundamentals of Semigroup Theory, p.13 and in M.Petrich, Introduction to Semigroups, a (partial)order is asymmetric, transitive and reflexive,
p.22, a left identity is called a unit, but in J.B.Fraleigh, A Sirst Course in Abstract Algebra, p.210 a unit is an element which has a multiplicative inverse
p.192 an element which is greater than or equal to every element in the set is called a unit or an identity
why the ambiguity?

Semigroups : an introduction to the structure theory / P.A. Grillet.

[Longhorn Review] Semigroups : an introduction to the structure theory / P.A. Grillet.

Material Type: All, Books — Tags: semigroups; — Posted on June 6, 2012, 9:12 am

By:

At the top of p.1 he states that "there are no other axioms" than associativity; at the bottom he states that "groups are semigroups" even though they have two other axioms. This type of terminology makes monoids be semigroups, and groups be monoids, and all of them be groupoids. This is like a physician identitying him- or herself as a highschool graduate, or Gen. McArthur as a graduate of West Point.

On page 4 line 13 he states "the reader will make sure that ...", and on page 5 line 2 from the bottom he states "the reader will happily verity that ..." - very, very peculiar verbiage for a math book which should be teaching not just listing tasks for "the reader".

On page 33, the term 'regular' is stated but its definition is hidden in the following Lemma - a peculiar mixture of definition and implications.

Wired [sound recording] / Jeff Beck.

[Longhorn Review] Wired [sound recording] / Jeff Beck.

Material Type: All, Music — Posted on April 25, 2012, 7:43 pm

By: Jeff Beck

"Wired" is simply one of the best slabs of wax in the fusion genre. The 1976 follow-up to Jeff's equally brilliant LP "Blow By Blow" (1975), "Wired" is the loudest, funkiest and altogether most sizzling of Beck's four fusion records in the 70's. Beck's tone is slinky and his phrasing fiery, as he trades licks with Jan Hammer and Max Middleton, two of the great keyboardists of the fusion-era. Beck's stunning interpretation of Mingus's gorgeous "Goodbye Porkpie Hat" remains a career high-water mark for the illustrious guitar wizard. However, Beck's playing was so consistently seminal throughout the 70's that his influence is hard to overstate...and "Wired" is an album that launched a thousand licks.

Truth [sound recording] / Robben Ford.

[Longhorn Review] Truth [sound recording] / Robben Ford.

Material Type: All, Music — Posted on April 25, 2012, 7:21 pm

By: Robben Ford

Robben Ford has rightly earned the deep respect of his peers through his deft, lyrical phrasing and incredible tone. "Truth" is a fine collection of mature and elegant jazz tinged blues, in the grand tradition of B.B. King, to whom Ford pays tribute in "Riley B. King". Mr. Ford's playing is deceptively complex. As a vocalist, Ford is less exciting but quite competent. His tunes, although rarely magical, are always good.

Their Eyes Were Watching God

[Longhorn Review] Their Eyes Were Watching God

Material Type: All, Books — Posted on February 13, 2012, 3:16 pm

By: Zoran Neale Hurston

I first read this book when I was 16 years old and have been in love with it ever since. The rollacoster of love that the main character, Janie goes through in the novel is tremendous but the love that she gets to share with Tea Cake is spectacular. This book should definitley be added to the list of love and romance for all ages! After you read it, you will never think about love the same again.

I'm your man [sound recording] Leonard Cohen.

[Longhorn Review] I'm your man [sound recording] Leonard Cohen.

Material Type: All, Music — Tags: romantic, staff pick, valentine's day recommendation — Posted on February 10, 2012, 3:43 pm

By: Leonard Cohen

I think the most seductive--mood creating songs for anytime but Valentine’s Day specifically are without a doubt Leonard Cohen's "I'm Your Man" from the album of the same title followed by his "Dance Me to the End of Love," found on Various Positions.
