what is the equivalent class for Mage_Page_Block_Html_Head in magento2?
I'm finding Magento\Theme\Block\Html\Header.
But there is no class related to Head.php

Update:

<?php
/**
 *
 */
class Gigya_Social_Block_Html_Head extends Mage_Page_Block_Html_Head {

  protected function _construct() {
    if (Mage::helper('Gigya_Social')->isPluginEnabled('gigya_global/gigya_global_conf')) { // check if gigiya plugin enabled
      $this->setTemplate('page/html/head.phtml'); // set output template

      $uriPrefix = !empty($_SERVER['HTTPS']) ? 'https://cdns' : 'http://cdn'; // check if domain is secured and set gigya domain accordingly
      $gigyaApiKey = trim(Mage::getStoreConfig('gigya_global/gigya_global_conf/apikey')); // get api key from store
      $name = $uriPrefix . '.gigya.com/JS/socialize.js?apikey=' . $gigyaApiKey; // set full socialize url
      $jsParams = array( // set config basic params (enabledProviders, lang, sessionExpiration, connectWithoutLoginBehavior)

There is no equivalent for that class in Magento2.
If you want to add something to the <head> tag you can use reference="head.additional".
For more details check the answer to this question: Magento 2: Adding Arbitrary HTML to the <head> of Every Page?
