Algebraic combinatorics.

Abstract. Combinatorial algebraic geometry comprises the parts of algebraic geometry where basic geometric phenomena can be described with combinatorial data, and where combinatorial methods are essential for further progress.

In English we use the word "combination" loosely, without thinking if the order of things is important. In other words: "My fruit salad is a combination of apples, grapes and bananas" We don't care what order the fruits are in, they could also be "bananas, grapes and apples" or "grapes, apples and bananas", its the same fruit salad.following well-loved objects in algebraic combinatorics andrepresentationtheory.

Algebraic combinatorics is a field of mathematics which was recognized "officially" 10-15 years ago. The name itself came from the Japanese mathematicians E. Bannai & T. Ito who published a book with such title in 1984. Roughly speaking, algebraic combinatorics deals with highly symmetrical combinatorial objects (graphs, designs, codes etc.). ...

Minimal skew semistandard Young tableaux and the Hillman-Grassl Correspondence Standard tableaux of skew shape are fundamental objects in enumerative and algebraic combinatorics and no product formula for the number is known. In 2014, Naruse gave a formula as a positive sum over excited diagrams of products of hook-lengths.
