This is not an answer, this is a message to @Gjergji Zaimi. Thank You very much. (And thank to dear  Wolfgang very much). Your answer is true with the version above. But if You see my comment to You and Wolfgang. I say that when $m=n$ the inequality 1 is [A Muirhead Like Inequality](https://mathoverflow.net/questions/303013/a-muirhead-like-inequality). The inequality 2 is [A Muirhead](https://www.cut-the-knot.org/arithmetic/algebra/MuirheadInequality.shtml).

So I see detail my question again (with Wolfgang help). I think the old version is not formulate true with my ideas, so may I re-formulate my ideas again as follows: 


>**Inequality 1:** Let $n>2$ and $1 \le m \le n$ be integers. Let $x_1, \dots, x_n$ and $y_1,\dots, y_n$ be nonnegative real numbers such that $(x_1,\dots, x_n)$ [majorizes](https://en.wikipedia.org/wiki/Majorization) $(y_1,\dots, y_n)$. Then for all reals $0 \leq a_1, a_2,\cdots,a_n \leq 1$, 

>$$\sum\limits_{sym}\left(  \sum\limits_{sym} x_{i_1}^{a_{p_1}} \cdots x_{i_m}^{a_{p_m}} \right) \leq \sum\limits_{sym}\left(  \sum\limits_{sym} y_{i_1}^{a_{p_1}} \cdots y_{i_m}^{a_{p_m}} \right) $$

* When $m=n$ this inequality is [A Muirhead Like Inequality](https://mathoverflow.net/questions/303013/a-muirhead-like-inequality)

>**Inequality 2:** Let $n>2$ and $1 \le m \le n$ be integers. Let $x_1, \dots, x_n$ and $y_1,\dots, y_n$ be nonnegative real numbers such that $(x_1,\dots, x_n)$ [majorizes](https://en.wikipedia.org/wiki/Majorization) $(y_1,\dots, y_n)$. Then for all reals $ a_1, a_2,\dots,a_n \geq 0$, 

> $$\sum\limits_{sym}\left(  \sum\limits_{sym} a_{i_1}^{x_{p_1}} \cdots a_{i_m}^{x_{p_m}} \right) \geq \sum\limits_{sym}\left(  \sum\limits_{sym} a_{i_1}^{y_{p_1}} \cdots a_{i_m}^{y_{p_m}} \right)$$

* When $m=n$ this inequality is [A Muirhead](https://www.cut-the-knot.org/arithmetic/algebra/MuirheadInequality.shtml)
