# tilting module
is any indecomposable projective-injective A-module a direct summand of tilting module
-
You are probable asking if such an indecomposable is a direct summand of every tilting module (for it surely is a direct summand of some tilting module: namely, the free tilting module $A$) if this were true, the... | {} |

### A new family of APN quadrinomials
Lilya Budaghyan, Tor Helleseth, and Nikolay Kaleyski
##### Abstract
The binomial $B(x) = x^3 + \beta x^{36}$ (where $\beta$ is primitive in $\mathbb{F}_{2^4}$) over $\mathbb{F}_{2^{10}}$ is the first known example of an Almost Perfect Nonlinear (APN) function that is not CCZ-equ... | {} |

# How do you find the x and y intercepts for 4x +3y-7=0?
Dec 18, 2015
$x$ intercept is $\frac{7}{4}$ and $y$ intercept is $\frac{7}{3}$.
#### Explanation:
For $y = 0$,
$\textcolor{w h i t e}{\times} 4 x - 7 = 0$
$\implies 4 x - 7 \textcolor{red}{+ 7} = 0 \textcolor{red}{+ 7}$
$\implies \textcolor{red}{\frac{1}{4} \... | {} |

In short, with this multiplicative definition, it could be ruled out the possibility that an individual's record would be randomly selected and published. Consider a malicious algorithm $M^*$ that picks a random individual's record from the input database (of size $n$) and outputs it. Note that this $M^*$ s... | {} |

# Large tilde over math symbol with automatic horizontal positioning
