How to can I access a variable in my main Controller, in controller of route?

//This is my main controller:
var app = angular.module('app', [
    'ui.router'
]);
app.controller('MyCtrl', function ($scope) {
    $scope.persons = [
        {name: 'Daisy', description: 'Developer'},
        {name: 'Zelda', description: 'Developer'},
        {name: 'Luide', description: 'Developer'},

    ];
});

This is my router config app.config(function ($stateProvider, $urlRouterProvider) { $urlRouterProvider.otherwise('/');

$stateProvider
    .state('list', {
        url: '/list',
        templateUrl: 'list.html',
        controller: 'MyCtrl'
    })
    .state('edit', {
        url: '/edit',
        templateUrl: 'edit.html',
        controller: function($scope, $state) {
            $scope.person = {name: "", description: ""};

            $scope.click = function () {
                $state.go('list');
            };
        }
    })
    .state('add', {
        url: '/add',
        templateUrl: 'edit.html',
        controller: function($scope, $state) {
            $scope.person = {name: "", description: ""};

            $scope.click = function () {
                // HOW TO CAN I ACCESS $SCOPE.PERSONS FOR MAKE THIS PUSH?
                $scope.persons.push($scope.person);
                $state.go('list');
            };
        }
    });

});

Rather than create $scope.persons in a MainController, it would probably be better to use a service to store the persons object:

app.service("People", function () {
   this.persons = [
        {name: 'Daisy', description: 'Developer'},
        {name: 'Zelda', description: 'Developer'},
        {name: 'Luide', description: 'Developer'},
        {name: 'Mario', description: 'Developer'}
    ];
});

Then you can inject this into your controllers (your code above):

.state('add', {
        url: '/add',
        templateUrl: 'edit.html',
        controller: function($scope, $state, People) {
            $scope.person = {name: "", description: ""};

            $scope.click = function () {
                //use persons object of people service.
                People.persons.push($scope.person);
                $state.go('list');
            };
        }
    });

});

You can share these persons across different controllers, services, and directives through Dependency Injection. For instance, your list controller (MyCtrl) would look as follows:

app.controller('MyCtrl', function ($scope, People) {
    $scope.persons = People.persons;
});
